00:00:00.220 --> 00:00:04.179
Coming up on StarTalk Special Edition, this one is on addiction.
2
00:00:05.160 --> 00:00:08.460
And we have as our special guest, Anna Lemke. She's
3
00:00:08.500 --> 00:00:12.560
a professor of psychiatry at Stanford University. And we discuss
4
00:00:13.140 --> 00:00:17.179
social media. Is that addicting? If it is, how does
5
00:00:17.239 --> 00:00:20.609
it addict us? We also talk about other emergent modern
6
00:00:20.649 --> 00:00:23.870
addictions like gambling. We've always known it was out there,
7
00:00:23.910 --> 00:00:26.269
but now it seems to be more prevalent than ever.
8
00:00:30.609 --> 00:00:33.759
What parts of your brain? And can we control it?
9
00:00:33.909 --> 00:00:36.490
Should we control it? Why is it there at all?
10
00:00:37.170 --> 00:00:40.869
Where did it come from evolutionarily? All that and more
11
00:00:41.490 --> 00:00:50.210
on StarTalk. This is StarTalk. Neil deGrasse Tyson here, your
12
00:00:50.289 --> 00:00:58.009
personal astrophysicist. And today it's a StarTalk special edition. Completely,
13
00:00:58.429 --> 00:01:03.880
completely devoted to to addiction. What does it mean? What
14
00:01:03.960 --> 00:01:06.530
role does it play in our lives? And is it good?
15
00:01:06.579 --> 00:01:07.200
Is it bad?
16
00:01:07.329 --> 00:01:08.849
Where did it come from? Where's it going?
17
00:01:10.010 --> 00:01:13.230
And before we introduce our special guest for this, let
18
00:01:13.250 --> 00:01:15.150
me get my co-host here, Chuck Nice.
19
00:01:15.209 --> 00:01:23.500
Chuck. Hey, Neil. Speaking of addiction, Chuck Nice. Okay, fine. Okay.
20
00:01:24.099 --> 00:01:25.260
We got Gary O'Reilly.
21
00:01:25.299 --> 00:01:25.659
Gary.
22
00:01:26.810 --> 00:01:27.980
Hi, Neil. Hey, good.
23
00:01:28.140 --> 00:01:31.959
Gary, former soccer pro and soccer sports announcer, and we got.
24
00:01:31.879 --> 00:01:33.060
Him for our show.
25
00:01:33.359 --> 00:01:37.900
We're borrowing him from all the others, from all the others. So, Gary,
26
00:01:38.780 --> 00:01:41.049
you and your fellow producers put this show together. What
27
00:01:41.060 --> 00:01:41.890
do you have in mind for us?
28
00:01:42.450 --> 00:01:46.549
And are you reaching out for help, Gary? Is this
29
00:01:47.090 --> 00:01:48.870
a clandestine cry for help?
30
00:01:50.469 --> 00:01:52.670
Yeah, this is all about me, darling.
31
00:01:52.689 --> 00:01:53.040
So....
32
00:01:56.180 --> 00:01:59.409
There are many things that we can get addicted to,
33
00:01:59.450 --> 00:02:02.290
which is alcohol, it's drugs, it's gambling, it's endless.
34
00:02:02.329 --> 00:02:03.689
Food, anything.
35
00:02:04.489 --> 00:02:04.930
And food.
36
00:02:05.069 --> 00:02:05.430
Food.
37
00:02:05.489 --> 00:02:09.830
So there are modern addictions, which we will get into
38
00:02:09.870 --> 00:02:12.020
later into the show. I mean, there's that point where
39
00:02:12.039 --> 00:02:15.520
you ask the question, does the relentless pursuit of pleasure
40
00:02:16.060 --> 00:02:19.919
always lead to pain? What role does dopamine and serotonin
41
00:02:19.960 --> 00:02:24.669
play in addiction? Have our minds been manipulated and tricked?
42
00:02:25.780 --> 00:02:30.699
into addictive behavioral patterns and what can be done to avoid,
43
00:02:30.800 --> 00:02:33.000
what can we do with our brains and stop them
44
00:02:33.060 --> 00:02:36.240
being rewired in sort of a case of social media.
45
00:02:36.259 --> 00:02:39.520
So for that, we're going to need someone really rather special.
46
00:02:39.780 --> 00:02:44.020
Chief of Stanford Addiction Medicine Dual Diagnosis Clinic at Stanford University,
47
00:02:44.879 --> 00:02:49.680
author of Drug Dealer MD and also Dopamine Nation. May
48
00:02:49.719 --> 00:02:51.659
I introduce Anna Lemke.
49
00:02:52.120 --> 00:02:53.840
Anna Lemke, welcome to StarTalk.
50
00:02:54.490 --> 00:02:56.849
Thank you for inviting me. I'm happy to be here.
51
00:02:57.870 --> 00:03:00.830
Yeah, and we learned that your background is as a psychiatrist,
52
00:03:01.330 --> 00:03:05.909
so you can authentically prescribe medicines in ways that many
53
00:03:06.090 --> 00:03:06.990
therapists cannot.
54
00:03:07.349 --> 00:03:12.389
The best kind of doctor. Only the best. The ones
55
00:03:12.430 --> 00:03:14.009
that can give you the good drugs.
56
00:03:15.069 --> 00:03:20.469
I'm delighted that you exist in this capacity because it's
57
00:03:20.509 --> 00:03:24.300
taken such a toll on society, not only in the past,
58
00:03:24.340 --> 00:03:28.810
but especially most recently. And let's take our first segment
59
00:03:29.469 --> 00:03:34.469
and focus on dopamine. First, is there such a thing
60
00:03:35.629 --> 00:03:39.500
as an addictive personality? Do some people release more dopamine
61
00:03:39.509 --> 00:03:42.039
than others when subject to the same stimulus?
62
00:03:43.599 --> 00:03:46.060
The short answer is yes. Yes.
63
00:03:46.680 --> 00:03:50.560
Yay. All right.
64
00:03:50.800 --> 00:03:54.789
But we don't use that terminology anymore, the terminology of
65
00:03:54.830 --> 00:03:59.889
the addicted personality. Now we talk more about people being
66
00:04:00.009 --> 00:04:03.860
vulnerable to addiction or having a genetic load for addiction.
67
00:04:03.879 --> 00:04:06.879
So we think of it more in the sort of
68
00:04:06.939 --> 00:04:13.520
disease model or the disease diathesis, rather than this person's personality.
69
00:04:13.879 --> 00:04:16.720
That makes sense when you think about it, because if
70
00:04:16.759 --> 00:04:20.509
you make it about a person's personality, then what you're
71
00:04:20.550 --> 00:04:25.170
doing is you're handing over control of the addiction to
72
00:04:25.250 --> 00:04:29.759
the person. when addiction is just the opposite of that,
73
00:04:30.259 --> 00:04:33.310
you will never meet an addict who says, hey man,
74
00:04:33.430 --> 00:04:35.990
I lost all my teeth, I lost

my job, I
75
00:04:36.050 --> 00:04:38.750
can't see my kids, but this is great.
76
00:04:39.129 --> 00:04:43.290
I wanna keep doing this. I wanna keep doing this.
77
00:04:43.310 --> 00:04:45.350
So tell me, what is dopamine specifically?
78
00:04:46.230 --> 00:04:49.379
So dopamine is a chemical that we make in our brains.
79
00:04:49.579 --> 00:04:52.079
It has many different functions, but one of the most
80
00:04:52.139 --> 00:04:56.709
important functions is that it's central to the experience of pleasure, reward,
81
00:04:56.949 --> 00:05:00.449
and motivation. And it may be even more important for
82
00:05:00.550 --> 00:05:03.310
motivation than for actual pleasure itself.
83
00:05:03.970 --> 00:05:04.829
Right.
84
00:05:04.889 --> 00:05:07.970
What do I hear about serotonin? When I hear about serotonin,
85
00:05:08.430 --> 00:05:09.990
is it synonymous with dopamine?
86
00:05:11.089 --> 00:05:15.089
It's not synonymous, but serotonin and dopamine are both neurotransmitters.
87
00:05:15.230 --> 00:05:19.410
Neurotransmitters are the molecules that bridge the gap between synapses
88
00:05:19.509 --> 00:05:24.050
to allow for finer tuning of our electrical circuits that
89
00:05:24.089 --> 00:05:27.230
make us who we are. And so dopamine and serotonin
90
00:05:27.350 --> 00:05:32.850
are related. They have distinct functions, however. And although serotonin
91
00:05:33.009 --> 00:05:36.500
is involved in mediating addiction to certain types of substances
92
00:05:36.540 --> 00:05:41.779
and behaviors, dopamine is considered the final common pathway for
93
00:05:42.079 --> 00:05:46.360
all reinforcing substances and behaviors, which is why neuroscientists tend
94
00:05:46.399 --> 00:05:49.199
to use it as a kind of universal currency for
95
00:05:49.290 --> 00:05:50.370
measuring addiction.
96
00:05:50.829 --> 00:05:53.990
So what triggers the release? What triggers the release, Professor,
97
00:05:54.269 --> 00:05:56.509
of the dopamine? Because it can't just be, you know what,
98
00:05:57.170 --> 00:06:00.050
brain says you have that now. Something must be triggering.
99
00:06:00.089 --> 00:06:00.449
Why can't it?
100
00:06:00.449 --> 00:06:02.850
Where is it triggering and what's it? Well, there you are.
101
00:06:02.889 --> 00:06:03.560
Why can't it?
102
00:06:04.449 --> 00:06:10.149
Yeah, so dopamine is released in response to reinforcing substances
103
00:06:10.209 --> 00:06:14.009
and behaviors. And by reinforcing, I mean things that are
104
00:06:14.610 --> 00:06:20.470
something that we deem necessary for survival, that typically feel good,
105
00:06:20.750 --> 00:06:23.240
or that our brains tell us this is important, you
106
00:06:23.269 --> 00:06:26.680
need to pay attention to it. So even like novelty,
107
00:06:27.199 --> 00:06:32.519
dopamine is very sensitive to novelty and newness. But for example, intoxicants,
108
00:06:32.639 --> 00:06:34.920
the sort of difference between something that is thought of
109
00:06:35.019 -->
00:06:38.040
as a drug or as very addictive and something that's
110
00:06:38.079 --> 00:06:41.319
thought of as not particularly addictive is how much dopamine
111
00:06:41.360 --> 00:06:43.959
is released in the reward pathway and how quickly it's released.
112
00:06:44.459 --> 00:06:47.600
And substances and behaviors that are highly addictive release a
113
00:06:47.620 --> 00:06:50.399
lot of dopamine all at once in this dedicated part
114
00:06:50.439 --> 00:06:51.920
of the brain called the reward pathway.
115
00:06:53.620 --> 00:06:59.050
Okay, reward pathway, new phrase, phrase of the day so far.
116
00:06:59.209 --> 00:07:01.629
What are we calling, what is a reward pathway? Is
117
00:07:01.649 --> 00:07:04.790
it simple as, it's a transmitter, it's how the delivery
118
00:07:04.829 --> 00:07:05.389
system works.
119
00:07:06.389 --> 00:07:09.649
Well, one of the exciting findings in neuroscience in the
120
00:07:09.689 --> 00:07:11.920
past hundred years or so is the discovery of a
121
00:07:12.019 --> 00:07:16.459
dedicated circuit in the brain that is central to this
122
00:07:16.620 --> 00:07:21.750
reward function, this motivation function. It consists broadly of of
123
00:07:21.790 --> 00:07:25.730
the nucleus accumbens and the ventral tegmental area. These are
124
00:07:25.829 --> 00:07:30.079
sort of basal forebrain nuclear structures. And then the prefrontal cortex,
125
00:07:30.459 --> 00:07:33.660
that large gray matter area right behind our foreheads. So
126
00:07:33.680 --> 00:07:37.420
that's a gross oversimplification. It's a very complex pathway. But
127
00:07:37.439 --> 00:07:42.240
that's in sort of reductionistic way what the reward pathway
128
00:07:42.279 --> 00:07:47.050
consists of. And that area is very rich in dopamine-releasing neurons.
129
00:07:47.310 --> 00:07:50.550
Right. So you gave us the location in the brain.
130
00:07:50.899 --> 00:07:53.740
where that occurs is what you're saying there. Is that right?
131
00:07:54.019 --> 00:07:54.439
That's right.
132
00:07:55.339 --> 00:08:02.329
Okay. But it's also that prefrontal cortex is also attached
133
00:08:02.410 --> 00:08:04.389
to our executive function, right?
134
00:08:04.790 --> 00:08:06.810
Exactly right. Yes.
135
00:08:07.029 --> 00:08:09.850
So that when that gets hijacked, then that puts us
136
00:08:10.009 --> 00:08:12.930
at risk of not being able to make the right
137
00:08:13.069 --> 00:08:16.319
decisions or to say no when we should say no
138
00:08:16.519 --> 00:08:21.290
or to be extremely capricious without even realizing why we're
139
00:08:21.329 --> 00:08:21.750
doing it.
140
00:08:22.430 --> 00:08:26.569
Yeah, very well said. So the prefrontal cortex is central
141
00:08:26.689 --> 00:08:31.540
to the ability to delay gratification, to appreciate future consequences,
142
00:08:32.000 --> 00:08:35.840
to tell autobiographical narratives or stories. And you might think
143
00:08:35.879 --> 00:08:38.360
of the prefrontal cortex as the brakes on the car
144
00:08:38.559 --> 00:08:41.259
and then the nucleus accumbens and ventral tegmental area, which
145
00:08:41.340 --> 00:08:45.019
is really rich in dopamine-releasing neurons, as the accelerator. So
146
00:08:45.059 --> 00:08:47.639
addiction is some kind of problem, either with the brakes
147
00:08:47.820 --> 00:08:49.139
or the accelerator or both.
148
00:08:50.039 --> 00:08:51.639
Wow. All right.
149
00:08:51.960 --> 00:08:57.870
So, Doctor, come across the phrase of dopamine rush.
150
00:09:00.289 --> 00:09:05.629
That's called cocaine, Gary. I'll handle this one for you, Doc. Yeah, Gary,
151
00:09:05.649 --> 00:09:09.509
that's called cocaine. We got that one. Chuck will take
152
00:09:09.529 --> 00:09:12.450
it from here. Chuck's got it from here. Yeah, okay.
153
00:09:12.549 --> 00:09:12.830
All right.
154
00:09:12.889 --> 00:09:13.309
I'm with you.
155
00:09:14.529 --> 00:09:17.289
They say when you get love struck, it's about a
156
00:09:17.330 --> 00:09:20.480
dopamine rush. So if we're falling in love, are we now,
157
00:09:21.039 --> 00:09:23.059
is it kind of that in a form of addiction?
158
00:09:24.179 --> 00:09:27.419
So maybe I can go back to some basic science experiments,
159
00:09:27.559 --> 00:09:30.799
looking at the response in terms of the release of
160
00:09:30.840 --> 00:09:35.259
dopamine to various stimuli. So we're always releasing dopamine at
161
00:09:35.279 --> 00:09:37.679
a kind of baseline tonic level. It's sort of like
162
00:09:37.700 --> 00:09:41.690
the heartbeat of the brain in some sense. But experiments
163
00:09:41.750 --> 00:09:45.210
in which a probe was stuck deep into this reward
164
00:09:45.230 --> 00:09:50.019
circuitry in rodents to measure dopamine release in response to
165
00:09:50.059 --> 00:09:55.279
different stimuli showed that dopamine firing increased above baseline 50%
166
00:09:55.279 --> 00:10:01.360
in response to chocolate, 100% in response to sex, 150%
167
00:10:01.360 --> 00:10:07.470
in response to nicotine, something like 225% in response to cocaine,
168
00:10:08.029 --> 00:10:12.409
and approximately 1,000% in response to methamphetamine. And indeed, if
169
00:10:12.730 --> 00:10:16.490
you match that behaviorally to whether or not a rodent
170
00:10:16.549 --> 00:10:20.120
will press a lever to get that substance or to
171
00:10:20.179 --> 00:10:23.240
engage in that behavior. You find that the more dopamine
172
00:10:23.279 --> 00:10:25.360
that's released, the more likely that rat is to press
173
00:10:25.399 --> 00:10:27.220
that lever until it dies.
174
00:10:28.159 --> 00:10:30.500
And when it comes to meth, they just rip the
175
00:10:30.539 --> 00:10:31.019
lever out.
176
00:10:31.440 --> 00:10:35.509
Right, essentially, essentially. Now, there is something a little artifactual
177
00:10:35.549 --> 00:10:38.490
about that in the sense that the way that meth
178
00:10:38.549 --> 00:10:43.779
works is to directly increase dopamine within the synapse.
whereas
179
00:10:43.820 --> 00:10:47.779
something like food or sex works through other chemical cascades
180
00:10:47.870 --> 00:10:51.450
like serotonin, for example, as we talked about. But the
181
00:10:51.509 --> 00:10:53.990
final common pathway, again, for all of these is to
182
00:10:54.049 --> 00:10:57.029
release dopamine, which is why neuroscientists like to use it
183
00:10:57.090 --> 00:10:58.730
as this kind of common currency.
184
00:10:59.190 --> 00:11:01.269
And that goes back to what you were saying earlier
185
00:11:01.309 --> 00:11:04.350
about motivation. So when we eat, we get a little
186
00:11:04.409 --> 00:11:09.100
hit of dopamine because that satisfaction allows us to say, hey,
187
00:11:09.360 --> 00:11:13.389
I should do this again. Otherwise, we've would just not eat.
188
00:11:13.409 --> 00:11:16.009
It would be like, yeah, whatever, who cares? Which is
189
00:11:16.049 --> 00:11:18.940
why sometimes when people are really depressed, one of the
190
00:11:18.980 --> 00:11:21.259
things they do not do is eat.
191
00:11:22.100 --> 00:11:25.299
Right, yeah, very well said. And furthermore, if I eat
192
00:11:25.659 --> 00:11:28.919
a piece of broccoli, I personally will get very little
193
00:11:28.960 --> 00:11:32.340
dopamine release, most likely. Neither does anyone.
194
00:11:32.360 --> 00:11:33.820
Neither will anyone.
195
00:11:33.860 --> 00:11:40.210
Right. Exactly. Exactly. But if I eat a chocolate cupcake,
196
00:11:40.370 --> 00:11:42.529
I'll get a lot more dopamine. But now, qualifying the
197
00:11:42.570 --> 00:11:46.230
broccoli idea, if I haven't eaten for two days and
198
00:11:46.250 --> 00:11:49.289
you give me a piece of broccoli, that's going to
199
00:11:49.330 --> 00:11:51.639
be really yummy to me, right? That's going to release
200
00:11:51.700 --> 00:11:56.340
more dopamine. at least from my baseline than not. I
201
00:11:56.700 --> 00:12:00.340
thought it was really important that Chuck talked about sort
202
00:12:00.360 --> 00:12:05.379
of other contextual factors like depression, right, which then sort
203
00:12:05.419 --> 00:12:11.169
of hypothetically decrease baseline dopamine firing levels such that almost
204
00:12:11.470 --> 00:12:16.929
everything loses its salience or its attractiveness. Likewise, other co-occurring
205
00:12:16.970 --> 00:12:20.409
mental health disorders can have other impacts on our experience
206
00:12:20.480 --> 00:12:23.509
of reward. It's thought, for example, that people with attention
207
00:12:23.570 --> 00:12:29.730
deficit disorder might be relatively insensitive to dopamine firing, which
208
00:12:29.769 --> 00:12:32.330
is why they maybe tend to be sensation seekers and
209
00:12:32.370 --> 00:12:36.220
need more rewards to get any kind of response.
210
00:12:35.879 --> 00:12:36.820
At all or furthermore.
211
00:12:36.840 --> 00:12:39.440
So everybody's got a different baseline. It's a baseline thing.
212
00:12:39.500 --> 00:12:43.299
Yeah, that's right. Everybody's got a different baseline.
213
00:12:43.360 --> 00:12:46.600
What I wanted to ask you, Professor, was with the
214
00:12:46.639 --> 00:12:49.840
meth being as addictive as it is, is it working
215
00:12:49.879 --> 00:12:54.220
purely to... detonate the dopamine or does it have other
216
00:12:55.379 --> 00:12:58.539
little techniques that are engaging and triggering?
217
00:12:59.779 --> 00:13:02.779
Well, it's, yeah, it's, you know, the talk about dopamine
218
00:13:02.870 --> 00:13:07.750
is like an oversimplification of a very complex process. You know,
219
00:13:08.350 --> 00:13:15.110
meth works through other chemical cascades, other neurotransmitters. Also, you know,
220
00:13:15.789 --> 00:13:19.000
when we look at these experiments in rodents, you know,
221
00:13:19.039 --> 00:13:20.600
rodents at the end of the day are not people.
222
00:13:21.129 --> 00:13:25.090
And our brains are much more complex and we cannot
223
00:13:25.129 --> 00:13:28.169
ignore the very important concept of drug of choice, which
224
00:13:28.230 --> 00:13:32.649
is to say my particular wiring might lead me to
225
00:13:32.700 --> 00:13:37.580
be more attracted to certain types of reinforcers that are different.
226
00:13:38.029 --> 00:13:41.200
from what your particular brain is wired for, such that
227
00:13:41.299 --> 00:13:46.159
I might work very, very hard to repeat the experience
228
00:13:46.200 --> 00:13:49.740
I have on social media, but not necessarily for meth
229
00:13:50.059 --> 00:13:53.370
or alcohol or something else because my wiring is just
230
00:13:53.450 --> 00:13:54.009
my wiring.
231
00:13:54.610 --> 00:13:59.230
Right, yeah. That's so wild because you hear people say
232
00:13:59.269 --> 00:14:02.090
it all the time. Well, I shouldn't say you hear
233
00:14:02.129 --> 00:14:04.340
people say it all the time. I've heard people say
234
00:14:04.379 --> 00:14:07.990
it often where- Oh, I tried this and it just
235
00:14:08.070 --> 00:14:11.789
did nothing for me. It just did. Yeah. Yeah. You know,
236
00:14:11.840 --> 00:14:16.100
I tried to have alcohol, but it did nothing for me. Or,
237
00:14:16.120 --> 00:14:18.940
you know, I, I smoked marijuana once. I mean, it
238
00:14:18.980 --> 00:14:21.240
just didn't do a damn thing to me. I got
239
00:14:21.320 --> 00:14:23.379
sleepy and that was it. So, you know, that's what
240
00:14:23.419 --> 00:14:25.539
you're talking about, which is kind of fascinating.
241
00:14:25.580 --> 00:14:25.820
Yeah.
242
00:14:25.840 --> 00:14:26.379
Fascinating.
243
00:14:27.379 --> 00:14:30.759
But Anna, what about, what of this, what of the, uh,
244
00:14:31.299 --> 00:14:37.259
the stereotype depressed person who just broke up with, A
245
00:14:37.279 --> 00:14:39.080
woman just breaks up with her boyfriend and you see her,
246
00:14:39.399 --> 00:14:41.600
this is in movies all the time, in rom-coms, where
247
00:14:41.620 --> 00:14:43.960
she's sitting on the bed eating a box of
chocolates
248
00:14:44.019 --> 00:14:47.679
looking at some sad movie. So they're eating in that
249
00:14:47.720 --> 00:14:49.919
case rather than not eating. Is that a different kind
250
00:14:49.940 --> 00:14:55.570
of depression that responds? So they're basically compensating for that
251
00:14:55.970 --> 00:14:59.730
loss of pleasure because now all they have access to
252
00:14:59.830 --> 00:15:00.970
is a box of chocolates.
253
00:15:01.990 --> 00:15:04.990
Yeah, so there are many different risk factors for addiction,
254
00:15:05.190 --> 00:15:09.850
but one very well-known risk factor is severe stress. So
255
00:15:09.909 --> 00:15:12.730
if we have some kind of giant stressor in our life,
256
00:15:13.509 --> 00:15:17.970
it's very natural for us to reflexively turn to substances
257
00:15:18.029 --> 00:15:22.009
or behaviors that will release those feel-good neurotransmitters as a
258
00:15:22.049 --> 00:15:26.230
way to cope or compensate. One of my favorite experiments
259
00:15:26.289 --> 00:15:31.940
in the neuroscience literature in rodents is... a group of
260
00:15:31.980 --> 00:15:35.899
rodents was trained to press a lever for intravenous cocaine.
261
00:15:36.620 --> 00:15:39.559
And rats and mice will press that lever until exhaustion
262
00:15:39.720 --> 00:15:44.019
or death. If you then take the cocaine away, eventually
263
00:15:44.279 --> 00:15:48.120
that behavior of pressing that lever will extinguish, which is
264
00:15:48.159 --> 00:15:50.679
to say they'll stop pressing the lever. But if you
265
00:15:50.720 --> 00:15:54.129
then expose that rat or that mouse to a severe
266
00:15:54.210 --> 00:15:58.309
painful foot shock, the rodent will immediately run over to
267
00:15:58.330 --> 00:15:59.830
the lever and start pressing it again.
268
00:16:00.490 --> 00:16:01.149
Whoa.
269
00:16:01.809 --> 00:16:05.830
So that's a very nice paradigm for what we as
270
00:16:05.870 --> 00:16:11.259
humans do, that stressor is something that can kick off, exacerbate,
271
00:16:11.299 --> 00:16:16.220
contribute to maladaptive consumptive behaviors. And for people who are
272
00:16:16.320 --> 00:16:19.440
in recovery or abstaining from their drug of choice, if
273
00:16:19.480 --> 00:16:23.980
they then experience acute stressor, they will almost reflexively turn
274
00:16:24.059 --> 00:16:26.919
to or want to turn to you know, their addictive
275
00:16:26.960 --> 00:16:29.299
behaviors as a way to shore themselves up again.
276
00:16:29.320 --> 00:16:30.419
That is fascinating.
277
00:16:31.080 --> 00:16:32.559
I'm glad you like it, Chuck.
278
00:16:33.259 --> 00:16:34.720
That is amazing.
279
00:16:35.240 --> 00:16:38.669
Did you use the phrase maladaptive consumptive behavior? Isn't that
280
00:16:38.690 --> 00:16:39.690
the same thing as overeating?
281
00:16:40.769 --> 00:16:45.789
Yeah, so maladaptive consumptive behavior can apply to almost anything.
282
00:16:46.250 --> 00:16:47.769
That's overeating. Okay.
283
00:16:48.409 --> 00:16:50.470
Or something that might not otherwise be good for you,
284
00:16:50.889 --> 00:16:56.679
whether or not it's food. Hi, I'm Neil deGrasse Tyson,
285
00:16:56.720 --> 00:16:58.679
your personal astrophysicist.
286
00:16:58.860 --> 00:17:02.679
And I'm Lindsay Nix-Walker, senior producer of StarTalk. And Neil
287
00:17:02.700 --> 00:17:05.960
and I just co-authored a brand new StarTalk book coming
288
00:17:06.059 --> 00:17:07.259
out September 12th.
289
00:17:07.960 --> 00:17:10.779
Yeah, this is the third in a series of collaborations
290
00:17:10.819 --> 00:17:15.230
with National Geographic Books. And this one is titled To
291
00:17:15.309 --> 00:17:20.390
Infinity and Beyond. And it's available for pre-order from the
292
00:17:20.490 --> 00:17:26.420
StarTalk website, startalkmedia.com slash books. If you pre-order it, you
293
00:17:26.440 --> 00:17:29.970
get to gain access to a live stream that Lindsay
294
00:17:30.009 --> 00:17:34.170
Walker and I will do from this office. And you
295
00:17:34.210 --> 00:17:38.289
have the occasion to submit questions that we will answer.
296
00:17:38.650 --> 00:17:42.789
That's right. If you pre-order from startalkmedia.com slash books, we'll
297
00:17:42.849 --> 00:17:46.309
answer your questions about the book, the universe, Neil's favorite
298
00:17:46.329 --> 00:17:47.789
kind of cheese, whatever you want.
299
00:17:49.849 --> 00:17:52.390
All right. So we'll see you there and we'll see
300
00:17:52.410 --> 00:17:52.690
you then.
301
00:17:57.700 --> 00:18:02.440
So, Professor, is there a way naturally or through intervention
302
00:18:02.500 --> 00:18:08.210
chemically to regulate, to manage this dopamine release rather than
303
00:18:08.250 --> 00:18:11.470
just have it gushing and be out of control? Sure.
304
00:18:11.589 --> 00:18:15.089
I mean, that's what treatment and recovery is all about.
305
00:18:16.589 --> 00:18:19.690
We think of addiction as a biopsychosocial disease. That means
306
00:18:19.730 --> 00:18:22.900
there are biological, psychological, and social risk factors, and we
307
00:18:22.920 --> 00:18:26.119
have to intervene at the biological, psychological, and social level.
308
00:18:26.819 --> 00:18:29.619
So in terms of the biological level, we have medicines
309
00:18:30.099 --> 00:18:33.359
that can treat addiction. For example, we use a medicine
310
00:18:33.400 --> 00:18:37.539
that blocks opioid receptors and it's FDA approved not just
311
00:18:37.579 --> 00:18:41.079
to treat opioid addiction, but also alcohol addiction because we
312
00:18:41.119 --> 00:18:44.039
know that alcohol works not just on the GABA systems,
313
00:18:44.079 --> 00:18:47.500
but also on our endogenous opioid systems. And by blocking
314
00:18:47.539 --> 00:18:51.039
the opioid receptor, what we're probably doing is blocking the
315
00:18:51.099 --> 00:18:54.900
reinforcing effects of alcohol such that people will describe that
316
00:18:54.940 --> 00:18:58.440
when
they drink, alcohol while they're taking naltrexone, it just
317
00:18:58.700 --> 00:19:01.940
doesn't taste as good. They're not as interested in having
318
00:19:02.440 --> 00:19:05.160
another drink, which is great because we can use it
319
00:19:05.200 --> 00:19:08.529
then to help people not just abstain, but to moderate
320
00:19:08.660 --> 00:19:11.630
their use. So that's one example of a biological intervention.
321
00:19:12.130 --> 00:19:15.130
Psychological interventions, there are many. One of the things we
322
00:19:15.190 --> 00:19:17.950
teach people is to kind of surf their urges or
323
00:19:18.049 --> 00:19:21.569
think through the drink. So these are like mindfulness practices
324
00:19:21.609 --> 00:19:24.809
so that they can learn to identify their triggers, not
325
00:19:24.869 --> 00:19:28.190
react to those triggers, to distance themselves, to wait those
326
00:19:28.250 --> 00:19:33.759
triggers out. And then in terms of social interventions, 12 Steps,
327
00:19:33.920 --> 00:19:38.319
Alcoholics Anonymous, Narcotics Anonymous, other 12 Step groups is basically
328
00:19:38.339 --> 00:19:43.509
a way to contextualize and socialize recovery so that you're
329
00:19:43.529 --> 00:19:45.970
in a sober social network so that you can reach
330
00:19:46.109 --> 00:19:49.609
out to another person when you're having urges or cravings
331
00:19:49.630 --> 00:19:52.759
and then that person can help you co-regulate. That's just
332
00:19:52.960 --> 00:19:55.529
one example of how 12-step works.
333
00:19:56.190 --> 00:19:58.430
Yeah, but if you know that there's chemistry going on
334
00:19:58.470 --> 00:20:00.589
in the brain, why would 12-steps work at all?
335
00:20:02.250 --> 00:20:07.650
Well, because 12-step changes brain chemistry. And we don't just, yeah, yeah.
336
00:20:07.730 --> 00:20:11.549
Is it more the social interaction or is it the
337
00:20:11.690 --> 00:20:16.859
disciplines that they introduce to your life? Or is it
338
00:20:17.059 --> 00:20:22.460
merely having a community around you that you're familiar with,
339
00:20:22.599 --> 00:20:26.869
that understands you, that brings you compassion? All these things
340
00:20:26.910 --> 00:20:29.849
that we tend to take for granted when we're living
341
00:20:30.490 --> 00:20:31.730
in normal social sets.
342
00:20:32.430 --> 00:20:34.230
I really think it's all of the above. So I
343
00:20:34.259 --> 00:20:38.619
think it's the foundational philosophy, the shifting the locus of
344
00:20:38.680 --> 00:20:43.119
control from inside of us to a power outside of ourselves,
345
00:20:43.160 --> 00:20:45.859
something greater than ourselves. It doesn't have to be a
346
00:20:45.940 --> 00:20:51.019
deified entity. It could just be the 12-step community. It's
347
00:20:51.059 --> 00:20:54.079
the working of the steps, all 12 of them, including
348
00:20:54.160 --> 00:20:57.569
especially step four, where we acknowledge what we have contributed
349
00:20:57.609 --> 00:21:00.410
to the problem and what our character defects are. which
350
00:21:00.450 --> 00:21:03.509
allow us to create a more valid narrative about our lives,
351
00:21:03.890 --> 00:21:07.240
which then also gives us access to more information to
352
00:21:07.279 --> 00:21:09.980
make better choices going forward. And then of course it
353
00:21:10.119 --> 00:21:13.519
is the social network, both the de-shaming that happens when
354
00:21:13.559 --> 00:21:16.740
you interact with other people struggling with addiction, but also
355
00:21:16.859 --> 00:21:20.400
as I talk about in my book, Dopamine Nation, a
356
00:21:20.440 --> 00:21:24.180
kind of leveraging the shame within the group such that
357
00:21:24.730 --> 00:21:27.009
people would not want to relapse because they would want
358
00:21:27.029 --> 00:21:29.440
to have to come back and declare themselves as as
359
00:21:29.480 --> 00:21:32.460
a newcomer, something that I label pro-social shame.
360
00:21:32.779 --> 00:21:37.200
So professor, when you've got these pathways and the dopamine
361
00:21:37.960 --> 00:21:43.019
is running and you talk about drug of choice, what
362
00:21:43.099 --> 00:21:45.880
else is out there that's triggering apart from some very
363
00:21:45.980 --> 00:21:47.099
obvious well-known ones?
364
00:21:48.240 --> 00:21:51.740
Well, it's important to recognize that you can get addicted
365
00:21:51.809 --> 00:21:56.009
not just to substances that we ingest, but also behaviors
366
00:21:56.089 --> 00:22:00.789
that we do. And because this motivational reward pathway is
367
00:22:00.849 --> 00:22:04.269
conserved over millions of years of evolution and across species,
368
00:22:04.690 --> 00:22:08.029
it's really fundamental to survival and to get us to
369
00:22:08.329 --> 00:22:12.910
be motivated to do anything. So theoretically, theoretically, you could
370
00:22:12.950 --> 00:22:16.140
get addicted to just about anything. And what we are
371
00:22:16.220 --> 00:22:18.900
seeing in the modern age, especially as more and more
372
00:22:18.960 --> 00:22:23.339
substances and behaviors have been made more potent, more reinforcing,
373
00:22:23.539 --> 00:22:27.829
more novel, more accessible, and come in greater and greater
374
00:22:27.890 --> 00:22:31.450
quantities is that we're seeing people get addicted to all
375
00:22:31.509 --> 00:22:34.130
kinds of things today that we would not have imagined
376
00:22:34.170 --> 00:22:36.920
possible in prior generations.
377
00:22:37.759 --> 00:22:43.559
Now, is it still considered an addiction if the behavior
378
00:22:43.720 --> 00:22:52.539
itself is not only acceptable, but maybe beneficial? I get
379
00:22:52.619 --> 00:22:54.779
up every day. By the way, this is an example, people.
380
00:22:54.819 --> 00:22:57.599
This is not my life. I get up every day
381
00:22:57.720 --> 00:23:00.440
at 6 a.m. and I head straight to the gym
382
00:23:00.460 --> 00:23:03.990
because my day isn't right unless I get up and
383
00:23:04.029 --> 00:23:07.250
head straight to the gym. And I do that. If
384
00:23:07.349 --> 00:23:09.690
I could do it seven days a week, I do
385
00:23:09.750 --> 00:23:11.970
it seven days a week. If I could go twice
386
00:23:12.009 --> 00:23:15.059
a day, I'd go twice a day. You know, if
387
00:23:15.099 --> 00:23:18.420
you meet a person like that, I mean, the behavior
388
00:23:18.500 --> 00:23:22.119
is seen as good. So we don't say, hey, man,
389
00:23:22.220 --> 00:23:23.660
you might have a problem.
390
00:23:24.700 --> 00:23:29.180
Yeah, an excellent point and a good opportunity to define addiction.
391
00:23:29.319 --> 00:23:32.920
Addiction is the continued compulsive use of a substance or
392
00:23:32.980 --> 00:23:37.349
behavior despite harm to self and or others. So just
393
00:23:37.410 --> 00:23:40.369
very broadly speaking, if we're diagnosing addiction, we have to
394
00:23:40.410 --> 00:23:43.039
identify that it's doing some kind of harm. It might
395
00:23:43.079 --> 00:23:45.859
be a harm that that person sees for themselves. It
396
00:23:45.900 --> 00:23:48.049
may be a harm that they don't recognize, but that
397
00:23:48.309 --> 00:23:52.849
others recognize. Having said that, you are absolutely right that
398
00:23:52.890 --> 00:23:56.170
this is contextualized within a given time and place, and
399
00:23:56.190 --> 00:23:59.490
that if society has deemed certain behaviors healthy, even when
400
00:23:59.549 --> 00:24:04.609
people do them to the detriment of their own health, potentially,
401
00:24:04.769 --> 00:24:09.660
or other people's harm, then we might not call it
402
00:24:09.900 --> 00:24:13.759
an addiction. And you use exercise, and people can actually
403
00:24:13.799 --> 00:24:16.250
get addicted to exercise, you know, where they're continuing to
404
00:24:16.309 --> 00:24:19.930
engage in that activity despite being injured, despite not spending
405
00:24:19.990 --> 00:24:23.710
time doing other things that they value. Workaholism is another
406
00:24:23.769 --> 00:24:29.210
great example, people who are compulsively focused on work, money, achievement,
407
00:24:29.640 --> 00:24:31.819
and one that we celebrate in our culture and that
408
00:24:31.859 --> 00:24:35.660
we usually don't call out. So addiction is an interesting
409
00:24:35.740 --> 00:24:38.920
field because there is this, what I think it's a
410
00:24:38.960 --> 00:24:42.640
fascinating intersection between culture and biology.
411
00:24:43.220 --> 00:24:48.099
So, Professor, if it's something that's core and necessary for life,
412
00:24:49.380 --> 00:24:51.200
say water, how about then?
413
00:24:52.420 --> 00:24:55.900
Well, so And if you're addicted to water, you are
414
00:24:55.920 --> 00:25:00.759
the most boring person in the world. You need help.
415
00:25:00.819 --> 00:25:06.880
It is tasteless. It has zero calories. And you'll pee
416
00:25:06.900 --> 00:25:08.500
a lot. Right.
417
00:25:10.019 --> 00:25:10.680
Yes.
418
00:25:10.700 --> 00:25:14.980
So, Professor, has that been a notified addiction?
419
00:25:15.569 --> 00:25:19.029
Yeah, so I've seen one case of that in my career.
420
00:25:19.410 --> 00:25:22.559
It was actually very sad. It was a woman... with
421
00:25:22.599 --> 00:25:26.079
a very severe alcohol addiction who got into recovery from
422
00:25:26.119 --> 00:25:28.900
her alcohol addiction. That is to say she was no
423
00:25:28.940 --> 00:25:32.390
longer consuming alcohol. She was actively working on her health.
424
00:25:32.990 --> 00:25:35.970
But somehow or another, she discovered that if she drank
425
00:25:36.190 --> 00:25:40.309
water in copious amounts, she could feel altered. And she
426
00:25:40.329 --> 00:25:44.700
got addicted to that process and ultimately died of hypo... Well,
427
00:25:44.839 --> 00:25:50.960
she had several very severe episodes of hyponatremia. and almost
428
00:25:51.000 --> 00:25:52.549
died from those episodes.
429
00:25:52.609 --> 00:25:55.369
Washing out the electrolytes. You can't drink that kind of water.
430
00:25:55.410 --> 00:25:55.769
No, no.
431
00:25:55.769 --> 00:25:59.829
Yeah, it's very dangerous. Holy crap, I was only joking.
432
00:25:59.869 --> 00:26:01.150
Now I feel like a jackass.
433
00:26:01.230 --> 00:26:02.309
No, no, it's okay.
434
00:26:02.329 --> 00:26:02.829
That's right.
435
00:26:04.730 --> 00:26:07.789
We're all learning, Chuck. We are all learning.
436
00:26:08.150 --> 00:26:10.589
Chuck is special. You guys are the worst.
437
00:26:12.750 --> 00:26:15.930
So Professor, then there's this term sort of dopamine cleansing,
438
00:26:16.150 --> 00:26:21.720
dopamine fasting. Didn't they used to call that cold turkey
439
00:26:21.759 --> 00:26:23.720
or something similar back in the day?
440
00:26:24.400 --> 00:26:25.259
I haven't heard that term.
441
00:26:25.279 --> 00:26:27.519
I haven't turned that term lately, cold turkey. Yeah, dopamine
442
00:26:27.660 --> 00:26:33.500
fastie and cold turkey. Nobody does anything cold turkey anymore.
443
00:26:34.079 --> 00:26:36.980
That used to mean that you had the right stuff.
444
00:26:37.759 --> 00:26:42.990
So we still do ask people to quit cold turkey
445
00:26:43.170 --> 00:26:46.609
as long as they're not at risk for life-threatening withdrawal.
446
00:26:47.119 --> 00:26:50.759
It's important to remember that people with severe physiologic dependence
447
00:26:50.819 --> 00:26:56.599
to alcohol, benzodiazepines like Xanax, or in some cases opioids,
448
00:26:57.400 --> 00:27:00.000
can have such a severe withdrawal syndrome that they could
449
00:27:00.059 --> 00:27:02.940
actually die from that withdrawal syndrome. So we would not
450
00:27:03.039 --> 00:27:05.900
ask that of people who were at risk of a
451
00:27:05.940 --> 00:27:09.529
life-threatening withdrawal. We also wouldn't ask people to stop abruptly
452
00:27:09.589 --> 00:27:11.549
if they had tried repeatedly to do that on their
453
00:27:11.589 --> 00:27:14.339
own
and weren't able to. But it is an intervention
454
00:27:14.519 --> 00:27:16.940
that we do use as kind of an early intervention
455
00:27:17.119 --> 00:27:20.680
for people who are a little bit addicted all the
456
00:27:20.720 --> 00:27:25.549
way up to moderately addicted but not yet severely physiologically dependent.
457
00:27:26.289 --> 00:27:28.670
And we ask them typically, you know, in clinic to
458
00:27:28.730 --> 00:27:32.250
sort of try to wrap their heads around stopping for
459
00:27:32.250 --> 00:27:34.950
30 days because 30 days is on average the amount
460
00:27:34.970 --> 00:27:37.369
of time it takes to sort of reset these dopamine
461
00:27:37.410 --> 00:27:41.390
reward pathways and to sort of get that prefrontal cortex
462
00:27:41.450 --> 00:27:44.619
back online. and be able to make informed decisions about
463
00:27:44.660 --> 00:27:46.000
what they want to do going forward.
464
00:27:46.460 --> 00:27:46.680
Okay.
465
00:27:46.720 --> 00:27:52.059
We've talked about dopamine and how if it gushes and rushes,
466
00:27:52.079 --> 00:27:54.799
you know, we've got a problem that we, we battle
467
00:27:54.819 --> 00:27:59.559
to control. What if naturally occurring within people's bodies, there's
468
00:27:59.619 --> 00:28:04.970
not enough, as you said, that baseline, what happens then? What, what,
469
00:28:05.269 --> 00:28:08.009
because it's got to be an undetrimental effect if it's
470
00:28:08.309 --> 00:28:12.769
below base. So what conditions come forward if there is,
471
00:28:12.849 --> 00:28:14.430
like I say, a lack of dopamine involved?
472
00:28:15.009 --> 00:28:17.849
Well, you know, this is, there's not a whole lot
473
00:28:17.910 --> 00:28:23.079
of deep understanding of this yet, but some preliminary data
474
00:28:23.099 --> 00:28:29.700
suggests that depression is characterized by low levels of dopamine transmission.
475
00:28:30.640 --> 00:28:34.319
As I said before, there's some thinking that people with
476
00:28:34.359 --> 00:28:38.230
attention deficit disorder might at baseline have lower levels of
477
00:28:38.269 --> 00:28:42.970
dopamine transmission, making them less sensible or sensitive to rewards.
478
00:28:44.710 --> 00:28:48.160
And we also know, very importantly, that with repeated exposure
479
00:28:48.240 --> 00:28:52.119
to highly reinforcing substances and behaviors that release a lot
480
00:28:52.140 --> 00:28:55.980
of dopamine all at once, the brain tries to adapt
481
00:28:56.180 --> 00:29:00.980
to that increased dopamine firing by down-regulating dopamine transmission, not
482
00:29:01.029 --> 00:29:04.630
just to baseline levels, but actually below baseline levels.
483
00:29:05.309 --> 00:29:07.829
So if you're a person who abuses a drug that
484
00:29:07.990 --> 00:29:12.190
floods your brain with dopamine, then your brain says, oh man,
485
00:29:12.450 --> 00:29:14.869
we're making too much dopamine. We got to chill out
486
00:29:14.950 --> 00:29:18.339
on this dopamine production. So then you stop doing the
487
00:29:18.380 --> 00:29:21.119
drug and all of a sudden you have no dopamine
488
00:29:21.140 --> 00:29:24.519
where you should have dopamine. And does that mean at
489
00:29:24.579 --> 00:29:27.460
that point you're like, man, I need some drugs because
490
00:29:27.480 --> 00:29:29.720
I need some dopamine. Some dopamine.
491
00:29:29.779 --> 00:29:33.390
That's exactly right, Chuck. You said it really, really well
492
00:29:33.509 --> 00:29:35.329
and more clearly than I could have.
493
00:29:35.970 --> 00:29:38.319
Um so anna why do we have you when we
494
00:29:38.359 --> 00:29:39.839
have chuck so he could have.
495
00:29:39.779 --> 00:29:45.640
Just honestly i've been thinking that myself this whole time
496
00:29:45.720 --> 00:29:49.960
i was like the comedian could basically give the talk
497
00:29:50.440 --> 00:29:52.460
okay um Yeah.
498
00:29:52.539 --> 00:29:57.069
That's exactly what happens is that with repeated use of
499
00:29:57.670 --> 00:30:01.529
the same or similar reinforcing substance and behaviors, we eventually
500
00:30:01.670 --> 00:30:04.569
end up in this kind of dopamine deficit state. Now
501
00:30:04.630 --> 00:30:07.119
we need more of our drug in more potent forms
502
00:30:07.619 --> 00:30:10.420
over time, not to get high, but just to feel
503
00:30:10.480 --> 00:30:14.000
normal and stop the cravings. which is exactly why people
504
00:30:14.039 --> 00:30:18.299
with severe addiction will relapse even weeks after they've stopped using,
505
00:30:18.380 --> 00:30:20.819
even though they can objectively tell you, yes, my life
506
00:30:20.880 --> 00:30:24.289
is much better because I'm not using and my spouse
507
00:30:24.329 --> 00:30:26.730
is back and my job is back. And I, you know,
508
00:30:26.869 --> 00:30:29.049
from a physical health point of view, I'm doing better.
509
00:30:29.410 --> 00:30:32.529
But mentally, many of them are still struggling with those
510
00:30:32.670 --> 00:30:40.009
universal symptoms of that dopamine deficit state, which are anxiety, irritability, insomnia, depression,
511
00:30:40.509 --> 00:30:44.569
and cravings. And craving manifests in many different ways. It
512
00:30:44.609 --> 00:30:47.750
can be ruminations to want to use. It can be
513
00:30:47.910 --> 00:30:52.779
long-winded narratives that are essentially rationalizations for why I should use.
514
00:30:53.539 --> 00:30:58.259
So craving is really a wily kind of thing that
515
00:30:58.740 --> 00:31:01.000
swims through our brain and catches us unaware.
516
00:31:01.680 --> 00:31:06.730
So Anna, if for some reason dopamine stopped getting made entirely,
517
00:31:07.230 --> 00:31:09.630
does that itself have consequences? Is that the life of
518
00:31:09.690 --> 00:31:12.240
a depressed person or is there some other symptoms of that?
519
00:31:13.579 --> 00:31:18.000
It depends what part of the brain dopamine production decreased in.
520
00:31:18.099 --> 00:31:21.460
So for
example, if we had a decrease in dopamine
521
00:31:21.480 --> 00:31:24.000
production in the part of the brain called the substantia nigra,
522
00:31:24.019 --> 00:31:26.839
which is a discrete and separate part from the reward pathway,
523
00:31:28.059 --> 00:31:30.319
then we would end up with Parkinson's disease, which is
524
00:31:30.460 --> 00:31:34.059
a movement disorder. So dopamine, as I said, has different
525
00:31:34.099 --> 00:31:38.240
functions and it's also very essential for movement. And it's
526
00:31:38.339 --> 00:31:41.960
probably no coincidence that that the same neurotransmitter that's important
527
00:31:42.000 --> 00:31:45.160
for movement is also important for pleasure, reward, and motivation
528
00:31:45.720 --> 00:31:49.059
because we typically need to move our bodies in order
529
00:31:49.140 --> 00:31:53.460
to get the reward that we want. Unfortunately, today, that's
530
00:31:53.720 --> 00:31:57.519
no longer necessarily true. We're now living in a time
531
00:31:57.559 --> 00:31:59.329
and place when we can just sit on the couch
532
00:31:59.400 --> 00:32:01.430
and swipe right and swipe left and have it delivered
533
00:32:01.930 --> 00:32:02.710
to the doorstep.
534
00:32:03.430 --> 00:32:06.329
Wait, so why can't you reverse engineer that and cure Parkinson's?
535
00:32:07.009 --> 00:32:08.710
You said there's a section of the brain, if it
536
00:32:08.730 --> 00:32:13.680
stops making dopamine, you have Parkinson's. So why not introduce
537
00:32:13.980 --> 00:32:16.519
dopamine back into the brain and then cure Parkinson's that way?
538
00:32:17.539 --> 00:32:22.069
So that's, in effect, how we do treat Parkinson's. So
539
00:32:22.269 --> 00:32:26.089
if you had Parkinson's and I gave you dopamine, a
540
00:32:26.130 --> 00:32:28.490
spoonful of dopamine, it would do absolutely nothing because it
541
00:32:28.509 --> 00:32:31.509
doesn't cross the blood-brain barrier. So instead, I have to
542
00:32:31.549 --> 00:32:35.730
give you something called L-DOPA, which is a dopamine precursor
543
00:32:35.750 --> 00:32:38.740
that does cross the blood-brain barrier. And then that gets
544
00:32:38.799 --> 00:32:42.220
converted into dopamine, which then gives you more dopamine in
545
00:32:42.240 --> 00:32:44.460
the substantia nigra, which then allows you to have more
546
00:32:44.539 --> 00:32:49.809
fluid movements to counteract the disease of Parkinson's. Unfortunately, it
547
00:32:49.910 --> 00:32:53.630
binds nonspecifically throughout the brain. So that means that that
548
00:32:53.670 --> 00:32:56.910
dopamine I gave you is now binding to dopamine receptors
549
00:32:56.950 --> 00:32:59.029
in the reward pathway. And what we see is about
550
00:32:59.069 --> 00:33:02.609
a quarter of people treated with L-DOPA for Parkinson's end
551
00:33:02.670 --> 00:33:07.849
up with some kind of compulsive, consumptive behavior, like pathological gambling,
552
00:33:07.910 --> 00:33:09.829
pathological shopping, et
cetera.
553
00:33:13.670 --> 00:33:16.369
Well, let's pick up some of the modern addictions that
554
00:33:16.390 --> 00:33:20.980
we see with gambling as legal lately as it's ever been.
555
00:33:21.000 --> 00:33:24.680
I see ads, I see And then, of course, the
556
00:33:24.799 --> 00:33:27.059
ads are accompanied with a little phone number at the bottom,
557
00:33:27.440 --> 00:33:29.759
have a gambling problem, call this. And I just think
558
00:33:29.799 --> 00:33:35.119
to myself, we have people exploiting the susceptibility of innocent
559
00:33:35.640 --> 00:33:40.769
members of the general public to gambling urges. And I'm
560
00:33:40.829 --> 00:33:45.750
saddened by this because they're hijacking our neurochemistry to make
561
00:33:45.789 --> 00:33:48.849
this happen. And of course, that also brings up social media,
562
00:33:49.269 --> 00:33:52.750
the addiction to how many likes you're going to get,
563
00:33:52.970 --> 00:33:57.970
what Could you just reflect on this modern emergence of
564
00:33:58.029 --> 00:34:01.359
addiction relative to the classical addictions we all grew up with?
565
00:34:02.299 --> 00:34:05.559
Yeah, so I'm equally sad. And I agree with you
566
00:34:05.680 --> 00:34:10.159
that these corporations are really preying on people who are
567
00:34:10.199 --> 00:34:14.389
vulnerable to addiction and also making us all, broadly speaking,
568
00:34:14.429 --> 00:34:18.969
more vulnerable to addiction. One of the biggest risk factors
569
00:34:19.030 --> 00:34:23.150
for addiction that people often discount is simple access. If
570
00:34:23.210 --> 00:34:25.150
you live in a neighborhood where drugs are sold on
571
00:34:25.170 --> 00:34:27.130
the street corner, you're more likely to try them and
572
00:34:27.150 --> 00:34:29.590
you're more likely to get addicted to them. And what
573
00:34:29.610 --> 00:34:33.719
we're seeing with gambling, especially for example, online sports betting,
574
00:34:33.739 --> 00:34:36.500
which has now become legal in multiple states in the union,
575
00:34:37.199 --> 00:34:39.920
is that in those states, we're seeing a 300 to
576
00:34:39.920 --> 00:34:45.119
500% increase in calls to pathological gambling hotlines. So it's
577
00:34:45.159 --> 00:34:50.340
very clear that as gambling becomes more accessible, especially through
578
00:34:50.389 --> 00:34:53.550
a mobile app, we are going to have more people
579
00:34:53.719 --> 00:34:57.300
who are struggling with gambling addiction. And very sadly, I
580
00:34:57.420 --> 00:35:01.059
would add to that, that these corporations actually often specifically
581
00:35:01.179 --> 00:35:04.099
prey on people who get addicted to gambling. So they
582
00:35:04.179 --> 00:35:07.619
track those people and they pursue them and they proffer.
583
00:35:07.639 --> 00:35:09.239
Because they can track them.
584
00:35:09.659 --> 00:35:12.900
Yeah, they give them money. They give them money to
585
00:35:13.000 --> 00:35:17.329
allow them to gamble. And they also change the algorithm
586
00:35:17.389 --> 00:35:19.920
to make sure that they win early on. And then
587
00:35:20.079 --> 00:35:22.940
by getting them hooked, then it's really, it's very.
588
00:35:23.079 --> 00:35:25.139
It's a classic drug dealer move.
589
00:35:25.199 --> 00:35:25.880
That's right.
590
00:35:26.159 --> 00:35:28.840
That's the oldest line in the book is the first
591
00:35:28.940 --> 00:35:30.030
one is always free.
592
00:35:30.489 --> 00:35:35.650
Right. Exactly right. So it's really, it's really, it's very distressing.
593
00:35:36.349 --> 00:35:40.250
So professor, you talked about movement being a trigger, right?
594
00:35:40.449 --> 00:35:44.989
Historically in our primal brain, we are now, the primal
595
00:35:45.010 --> 00:35:48.409
brain that we have is now fighting some serious modern technologies.
596
00:35:48.900 --> 00:35:52.139
So I'm going to upgrade to cartoon garish colors. I'm
597
00:35:52.159 --> 00:35:53.909
going to give you movement. I'm going to give you...
598
00:35:54.519 --> 00:35:57.500
How many other strategies are out there that are keeping
599
00:35:57.699 --> 00:35:58.440
my attention?
600
00:35:58.480 --> 00:35:59.010
Because that's the.
601
00:35:59.260 --> 00:36:02.050
For me, the product that's generated in social media is
602
00:36:02.139 --> 00:36:03.849
my attention time. Right.
603
00:36:03.869 --> 00:36:05.070
It's the new currency. They can do that.
604
00:36:05.510 --> 00:36:05.929
Yeah. Yeah.
605
00:36:06.920 --> 00:36:07.389
That is it.
606
00:36:07.480 --> 00:36:11.659
So how are they making sure I am utterly fixated?
607
00:36:11.719 --> 00:36:14.630
Yes, and please take your time explaining this so that
608
00:36:14.690 --> 00:36:20.449
I can take notes for my own social media accounts.
609
00:36:20.469 --> 00:36:21.750
All right.
610
00:36:22.449 --> 00:36:26.280
Yeah, so you're getting at, you know, what is one
611
00:36:26.300 --> 00:36:31.340
of the huge issues in considering these digital devices and
612
00:36:31.380 --> 00:36:37.690
these digital media as... as having genuine product liability. Just
613
00:36:37.710 --> 00:36:41.880
the way that we think of cigarettes as having inherent harm,
614
00:36:42.320 --> 00:36:45.139
there's now a shift toward thinking about the inherent harm
615
00:36:45.340 --> 00:36:48.599
of digital media of all sorts because of the built-in
616
00:36:48.679 --> 00:36:52.480
design functions. And I think the first and foremost, the
617
00:36:52.659 --> 00:37:00.179
design function of 24-7 portable accessibility that increases access wherever
618
00:37:00.239 --> 00:37:04.469
we are, whenever we are, has made an enormous impact
619
00:37:05.110 --> 00:37:08.070
on the addictive potential and the number of people struggling
620
00:37:08.090 --> 00:37:12.469
with digital addiction, addiction to technology and to the internet.
621
00:37:12.650 --> 00:37:17.820
So in the early 2000s, with the advent of smartphones,
622
00:37:18.960 --> 00:37:21.599
we saw a huge increase in the number of people
623
00:37:21.619 --> 00:37:27.469
struggling with addictive, pathological gambling, pornography viewing, And then as
624
00:37:27.530 --> 00:37:30.389
time went on, we started to see video, addictive video
625
00:37:30.409 --> 00:37:33.269
game use, addictive shopping, addictive social media use.
626
00:37:33.670 --> 00:37:35.809
It's because they could take it with them. It's with
627
00:37:35.829 --> 00:37:36.739
them at all times.
628
00:37:36.840 --> 00:37:39.820
That's right. That's a huge part of it that people,
629
00:37:39.840 --> 00:37:42.940
I think, really don't fully appreciate. And it's important to
630
00:37:43.000 --> 00:37:45.559
realize that because that means that the intervention is going
631
00:37:45.619 --> 00:37:48.800
to be separating ourselves for some period of time every
632
00:37:48.840 --> 00:37:51.690
day from our digital devices. And that's what we're not doing.
633
00:37:51.710 --> 00:37:55.409
We're basically almost cybernetically enhanced with our devices with us
634
00:37:55.469 --> 00:37:55.929
at all times.
635
00:37:56.480 --> 00:37:58.980
That's so true, because in the 80s, when I was
636
00:37:59.059 --> 00:38:02.030
growing up, if you wanted to take porn with you,
637
00:38:02.179 --> 00:38:05.329
that was really quite an undertaking. Right, good luck.
638
00:38:05.690 --> 00:38:06.869
Good luck, right?
639
00:38:08.309 --> 00:38:08.570
Yes.
640
00:38:09.010 --> 00:38:13.610
So, Professor, how do you ensure security of the mind,
641
00:38:14.010 --> 00:38:16.159
particularly in the younger age groups?
642
00:38:16.679 --> 00:38:17.739
I like that phrase, yeah.
643
00:38:17.900 --> 00:38:22.579
And how do you get that holistic protection?
644
00:38:23.480 --> 00:38:23.619
What.
645
00:38:24.239 --> 00:38:27.190
What levels of engagement and where does it come from
646
00:38:27.289 --> 00:38:29.349
for this to be something we can carry forward?
647
00:38:29.369 --> 00:38:30.650
You got to lock your kids in a box.
648
00:38:31.230 --> 00:38:32.489
Yeah, so yeah, exactly.
649
00:38:32.530 --> 00:38:35.389
Wait a minute. You don't do that already? Am I
650
00:38:35.429 --> 00:38:39.210
the only one that does that? Wait. Is there something
651
00:38:39.230 --> 00:38:39.889
wrong with that?
652
00:38:41.030 --> 00:38:41.730
Oh, no.
653
00:38:42.710 --> 00:38:43.469
I think J.K.
654
00:38:43.510 --> 00:38:46.050
Rowling got there before us.
655
00:38:46.079 --> 00:38:47.940
Harry Potter under the stairs.
656
00:38:48.199 --> 00:38:49.940
Yeah, I mean, first of all, I want to say
657
00:38:49.980 --> 00:38:53.860
that this is both an individual problem and a collective problem.
658
00:38:54.230 --> 00:38:57.949
That means we need both bottom-up solutions where we individually
659
00:38:58.070 --> 00:39:02.980
change our habits as individuals and as families, but we
660
00:39:03.019 --> 00:39:08.199
also need top-down interventions, schools,
corporations that make and profit
661
00:39:08.340 --> 00:39:11.780
from the media and the devices, the federal government who
662
00:39:11.800 --> 00:39:14.840
can impose regulations. It needs to be coming from both
663
00:39:14.980 --> 00:39:17.480
ends in order for us to get a handle on
664
00:39:17.519 --> 00:39:23.250
this huge worldwide collective problem. And specifically in terms of
665
00:39:23.309 --> 00:39:26.730
what can be done beyond the kinds of individual and
666
00:39:26.789 --> 00:39:29.329
family interventions that I talk about in my book, when
667
00:39:29.349 --> 00:39:31.699
you think about it from a policy perspective, I think
668
00:39:31.739 --> 00:39:34.460
about it as in three categories. We can try to
669
00:39:34.519 --> 00:39:38.539
change the design, which is what you were talking about earlier, Gary,
670
00:39:39.780 --> 00:39:42.579
this idea of like the bottomless bowls, the flashing lights,
671
00:39:43.119 --> 00:39:45.800
the AI algorithms that learn what we've liked before and
672
00:39:45.820 --> 00:39:50.340
then push content similar but slightly different than what we've
673
00:39:50.360 --> 00:39:54.480
watched before, which then keeps people's engagement, their attention, makes
674
00:39:54.519 --> 00:39:58.690
it more compulsive, pushes them to extreme versions, more potent versions.
675
00:39:59.090 --> 00:40:02.150
So we need to change the design in order to
676
00:40:02.210 --> 00:40:06.550
decrease the liability of the products. We also need to
677
00:40:06.590 --> 00:40:11.719
think about access. So limiting access, as we've talked about,
678
00:40:12.389 --> 00:40:14.860
It's not just what we're doing online. It's the sheer
679
00:40:14.960 --> 00:40:18.360
quantity and frequency of viewing that screen, which is changing
680
00:40:18.420 --> 00:40:22.340
our brains and leading to morbidity and mortality. And when
681
00:40:22.360 --> 00:40:25.780
I think of access, really low-hanging fruit, in my opinion,
682
00:40:25.860 --> 00:40:29.090
is the school system. It seems to me very obvious
683
00:40:29.510 --> 00:40:33.670
that children should not be having their smartphones with them
684
00:40:34.070 --> 00:40:38.250
during school hours, especially not during class, but also potentially
685
00:40:38.309 --> 00:40:41.059
not at all. And what we're seeing is some schools,
686
00:40:41.320 --> 00:40:44.590
typically private schools that have more resources, have taken phones
687
00:40:44.670 --> 00:40:47.389
away and given their students flip phones. And what you're
688
00:40:47.409 --> 00:40:50.929
hearing is you're hearing about huge improvements in student well-being
689
00:40:50.949 --> 00:40:54.530
and student mental health. You're hearing teachers and administrators say
690
00:40:54.860 --> 00:40:56.559
the schools are noisy again.
691
00:40:56.679 --> 00:40:56.940
Why?
692
00:40:57.000 --> 00:41:01.280
Because kids... are engaging with each other. So this is.
693
00:41:01.340 --> 00:41:03.320
So a flip phone is just a phone. It's not.
694
00:41:03.840 --> 00:41:06.539
It's boring. It's boring. A kid's not going to spend
695
00:41:06.579 --> 00:41:07.679
their time on a flip phone.
696
00:41:07.739 --> 00:41:09.940
But they can't complain that they don't have phone access
697
00:41:09.980 --> 00:41:11.480
to an emergency call.
698
00:41:11.179 --> 00:41:13.500
To home or something. That's exactly right.
699
00:41:13.619 --> 00:41:15.900
So how much of this is covered in your Dopamine
700
00:41:15.940 --> 00:41:18.139
Nation book, which came out just a couple.
701
00:41:18.019 --> 00:41:18.519
Of years ago?
702
00:41:19.500 --> 00:41:22.949
Dopamine Nation focuses very much on what we as individuals
703
00:41:23.159 --> 00:41:26.510
and we as families can do And it describes in
704
00:41:26.570 --> 00:41:29.610
simple terms the neuroscience of what's happening and why we
705
00:41:29.630 --> 00:41:33.769
get addicted to potentially almost anything, and then specifically steps
706
00:41:33.829 --> 00:41:37.230
that we can take. So it's not much focused on policy.
707
00:41:37.610 --> 00:41:39.829
But since it came out, I've been more and more
708
00:41:39.869 --> 00:41:46.409
involved in policy discussions, and trying to consider what can
709
00:41:46.429 --> 00:41:49.090
be done beyond the level of the individual and the
710
00:41:49.130 --> 00:41:49.889
individual family.
711
00:41:49.909 --> 00:41:53.170
And what about family policy? Because I'm sure right now,
712
00:41:53.269 --> 00:41:56.849
anybody who's a parent who is listening to this is thinking,
713
00:41:57.610 --> 00:42:00.210
it's impossible for me to stop my kids or get
714
00:42:00.250 --> 00:42:02.460
them off of the video games, to get them off
715
00:42:02.659 --> 00:42:05.460
of the tablet, to stop them from... And by the way,
716
00:42:05.519 --> 00:42:09.320
there's social media companies now push out all the content everywhere.
717
00:42:09.659 --> 00:42:12.150
So if you keep your kids off of X, Twitter,
718
00:42:12.190 --> 00:42:15.050
whatever that is, or Facebook or whatever, they're just going
719
00:42:15.070 --> 00:42:18.130
to get it on YouTube or YouTube Shorts or whatever,
720
00:42:18.789 --> 00:42:25.150
or on Discord. So what do you do to curtail,
721
00:42:25.650 --> 00:42:29.010
aside from the draconian measure of ripping the phone away
722
00:42:29.050 --> 00:42:31.599
from them, what do you do to curtail their behavior?
723
00:42:32.139 --> 00:42:32.940
You put them in a box.
724
00:42:34.619 --> 00:42:39.019
We already talked that.
725
00:42:40.340 --> 00:42:43.110
You know, you don't put the kid in the box,
726
00:42:43.150 --> 00:42:45.949
but you probably should put the devices in a box.
727
00:42:46.610 --> 00:42:49.809
Oh, so you, you are an advocate of literally snatching
728
00:42:49.869 --> 00:42:50.510
it away from them.
729
00:42:50.630 --> 00:42:53.679
So let me, let me qualify that for kids up
730
00:42:53.739 --> 00:42:56.980
until a
certain age. And I would say this is
731
00:42:57.059 --> 00:43:00.809
usually around 11 or 12. I believe that we as
732
00:43:00.869 --> 00:43:05.150
parents still have enough control, generally speaking, in the household,
733
00:43:05.250 --> 00:43:08.530
especially if we're co-parenting with somebody that agrees with us
734
00:43:08.610 --> 00:43:12.389
and we can organize it together. And I think it's
735
00:43:12.429 --> 00:43:15.280
very possible and also good to sit down as a
736
00:43:15.300 --> 00:43:18.639
family and say, hey, we've been using devices in this way,
737
00:43:18.800 --> 00:43:21.920
but it's not healthy. And here are the reasons why.
738
00:43:22.000 --> 00:43:24.699
And so as a family, we need to make some changes.
739
00:43:24.820 --> 00:43:27.420
And I've seen families do this. And it can be
740
00:43:27.559 --> 00:43:30.639
very distressing for all comers because very often parents are
741
00:43:30.699 --> 00:43:33.039
as addicted as kids. But to do it together as
742
00:43:33.079 --> 00:43:36.619
a family with younger children can be so healthy for
743
00:43:36.679 --> 00:43:39.789
families to just really reorient. It doesn't mean your kid's
744
00:43:39.849 --> 00:43:42.409
never on the device, but they're on the device for
745
00:43:42.429 --> 00:43:45.210
a limited quantity of time after they've done their chores
746
00:43:45.230 --> 00:43:47.670
and their schoolwork as a kind of thing that they've
747
00:43:47.889 --> 00:43:50.809
earned for good behavior for a limited amount of time
748
00:43:50.969 --> 00:43:53.070
and not every day. And then not every day is
749
00:43:53.170 --> 00:43:56.039
really key. If you want a number of hours There's
750
00:43:56.360 --> 00:44:00.800
some general consensus less than two hours a day. Now,
751
00:44:00.960 --> 00:44:03.440
once you, I know, and I'm talking, and I'm not.
752
00:44:03.480 --> 00:44:06.449
Talking about you. Wait, who's going to raise my kids
753
00:44:06.489 --> 00:44:08.070
if they're only allowed to watch this?
754
00:44:08.090 --> 00:44:10.849
Yeah, exactly. But it's important. It's important to get in
755
00:44:10.869 --> 00:44:14.070
there while they're little because it lays the foundation for,
756
00:44:14.230 --> 00:44:17.989
you know, their wiring and their neurological scaffolding that they're
757
00:44:18.010 --> 00:44:20.849
going to be left with the rest of their adult lives. Now,
758
00:44:21.010 --> 00:44:25.500
once kids get to be about 13, they're no longer
759
00:44:25.539 --> 00:44:27.780
in your control. They're going to do what they're going
760
00:44:27.800 --> 00:44:29.940
to do. But at that point, what we can do
761
00:44:30.000 --> 00:44:32.340
as parents is model the behavior that we want to see,
762
00:44:32.820 --> 00:44:36.960
give them feedback on what we're observing, use contingency management,
763
00:44:37.019 --> 00:44:41.780
which is punishments and rewards to incentivize the kinds of
764
00:44:41.820 --> 00:44:44.190
behaviors that we want to see, and just talk about
765
00:44:44.210 --> 00:44:46.769
it openly as a family and try to have a
766
00:44:46.789 --> 00:44:51.070
certain tech etiquette around when it's appropriate to use devices
767
00:44:51.110 --> 00:44:53.690
and when it's not. When we're having friends over for
768
00:44:53.710 --> 00:44:56.869
a meal, you shouldn't be on your device. You should
769
00:44:56.909 --> 00:45:00.150
be looking them in the eye, greeting them, spending some
770
00:45:00.190 --> 00:45:03.230
time talking, not just being. So I think these are
771
00:45:03.250 --> 00:45:05.409
the conversations we really have to have.
772
00:45:05.989 --> 00:45:09.110
Yeah, but does that mean there's no hope through legislation
773
00:45:09.190 --> 00:45:12.699
or Congress or lobbying the companies themselves?
774
00:45:13.300 --> 00:45:17.559
Oh, absolutely. That's the third piece of it is hold
775
00:45:17.579 --> 00:45:20.809
the corporations accountable. And the way to do that is
776
00:45:20.869 --> 00:45:26.599
really through various types of nudges through policy reform and regulations.
777
00:45:27.079 --> 00:45:30.639
And just to give an example, I talked about thinking
778
00:45:30.679 --> 00:45:34.880
that kids should have as a top-down policy no smartphones
779
00:45:35.039 --> 00:45:39.829
during school hours. And, you know, the federal government could
780
00:45:39.889 --> 00:45:43.590
do that by, they give lots of funds to public schools.
781
00:45:43.610 --> 00:45:45.829
You know, they could say either we're not going to
782
00:45:45.889 --> 00:45:48.869
give you as much of those funds unless you manage
783
00:45:49.800 --> 00:45:52.099
technology in your school in a different kind of way.
784
00:45:52.219 --> 00:45:53.900
Or they could sweeten the pot and say, we will
785
00:45:53.920 --> 00:45:58.619
give you more funds if you do something like implement
786
00:45:58.699 --> 00:46:03.110
some kind of new smartphone use policy in your school.
787
00:46:03.469 --> 00:46:05.969
So there are ways to get in there. And there
788
00:46:05.989 --> 00:46:08.409
are precedents as well. So for example, the age 21
789
00:46:08.409 --> 00:46:12.389
drinking laws, which are now universal in every state, really
790
00:46:12.449 --> 00:46:14.730
came to be because the federal government said, well, we're
791
00:46:14.750 --> 00:46:17.449
not going to give you highway funds if you keep
792
00:46:17.469 --> 00:46:20.469
your drinking age lower. So there are ways to kind
793
00:46:20.510 --> 00:46:21.679
of create these nudges.
794
00:46:22.320 --> 00:46:22.920
To strong arm.
795
00:46:23.000 --> 00:46:27.460
So professor, they're called smartphones, right? There must be a way.
796
00:46:27.539 --> 00:46:29.860
I mean, I'm not technically gifted in any way, but
797
00:46:30.019 --> 00:46:32.119
you build in a phone and you've got to have
798
00:46:32.159 --> 00:46:35.489
a trust program here where if it's going to a
799
00:46:35.530 -->
00:46:37.909
young person under the age of 11 or 10, say
800
00:46:37.929 --> 00:46:41.210
like that, then it gets time to shut down on
801
00:46:41.369 --> 00:46:43.889
usage per day? As you said, no more than two
802
00:46:43.929 --> 00:46:45.210
hours or whatever the limit might be.
803
00:46:45.230 --> 00:46:46.710
Yeah, there are apps for that. Surely there is a
804
00:46:46.750 --> 00:46:49.030
way for that. Yeah, they do.
805
00:46:49.070 --> 00:46:50.719
They must then be mandatory.
806
00:46:51.010 --> 00:46:54.159
Well, there are lots of software apps that do that,
807
00:46:54.199 --> 00:46:57.139
but these kids very early on figure out all kinds
808
00:46:57.179 --> 00:46:57.659
of workarounds.
809
00:46:57.679 --> 00:46:58.960
All kinds of ways of workarounds.
810
00:46:59.039 --> 00:47:02.360
But what you're implying is actually something that I don't
811
00:47:02.400 --> 00:47:05.199
think has been done to any great degree, which is
812
00:47:05.280 --> 00:47:08.559
that there should be hardware implementation. So, for example, I
813
00:47:09.519 --> 00:47:12.659
I'm not an engineer or a computer science person, but
814
00:47:12.699 --> 00:47:17.329
I can imagine a school laptop that might help, especially
815
00:47:17.389 --> 00:47:20.949
for younger children, avoid some of the content that we
816
00:47:20.989 --> 00:47:24.570
want them to avoid. So not just expecting software companies,
817
00:47:24.610 --> 00:47:27.250
but also hardware companies. But this gets to the whole
818
00:47:27.309 --> 00:47:33.469
content issue, which is very hard to regulate because it's
819
00:47:33.530 --> 00:47:36.510
in direct conflict with privacy laws. So for example, in
820
00:47:36.610 --> 00:47:40.360
some states, I think Louisiana is one of them, they've
821
00:47:40.400 --> 00:47:42.719
implemented a law that says in order to sign up
822
00:47:42.760 --> 00:47:46.679
for a website like Pornhub, you have to prove that
823
00:47:46.739 --> 00:47:49.090
you are, I think, 21, and you have to do
824
00:47:49.130 --> 00:47:52.090
that by uploading your driver's license. But of course, nobody
825
00:47:52.130 --> 00:47:53.929
is going to go on Pornhub wants to upload their
826
00:47:53.969 --> 00:47:56.719
driver's license and be associated with having done that. So
827
00:47:56.760 --> 00:47:59.519
now they've worked out having like these third party sites,
828
00:47:59.659 --> 00:48:02.000
which kind of anonymously process.
829
00:48:02.019 --> 00:48:05.260
You can register with the third party site and your
830
00:48:05.320 --> 00:48:08.030
registration with that third party site allows you access to
831
00:48:08.050 --> 00:48:08.989
the porn site.
832
00:48:09.050 --> 00:48:09.670
That's it.
833
00:48:09.690 --> 00:48:11.710
Chuck, why do you know that? Chuck, why do you
834
00:48:11.989 --> 00:48:15.349
know that? Because I have a very good friend in Louisiana.
835
00:48:15.550 --> 00:48:20.349
You got a friend. You've got a friend. Okay. All
right.
836
00:48:20.849 --> 00:48:21.030
Okay.
837
00:48:21.050 --> 00:48:24.230
So, Professor, let's get to the content aspect. I mean,
838
00:48:24.289 --> 00:48:28.070
it's not just the porn or online gambling. There is
839
00:48:28.269 --> 00:48:33.769
extreme content that comes through, and it is getting extreme
840
00:48:33.829 --> 00:48:35.210
reactions from individuals.
841
00:48:35.230 --> 00:48:36.250
You're a psychiatrist.
842
00:48:37.110 --> 00:48:42.139
Are we hardwired to react extremely to extreme content?
843
00:48:43.179 --> 00:48:46.019
Let me sharpen that question. I'm all with it, but
844
00:48:46.039 --> 00:48:47.940
I want to tune it specifically because we've got to.
845
00:48:48.269 --> 00:48:52.409
wrap this up very shortly, is we are seeing content.
846
00:48:52.449 --> 00:48:55.699
Forget the kids now. The adults are being fed content
847
00:48:55.820 --> 00:49:01.519
by the algorithm that enrages us and motivates us to
848
00:49:01.960 --> 00:49:06.320
act in some way. And in the limiting case, it
849
00:49:06.360 --> 00:49:08.840
motivates us to commit violence against some group.
850
00:49:08.860 --> 00:49:10.250
We're going to the Capitol.
851
00:49:13.969 --> 00:49:18.789
So this is not so much addiction, but there's definitely
852
00:49:18.829 --> 00:49:22.039
a brain thing going on. on there that's being fed
853
00:49:22.639 --> 00:49:24.599
and that we can, we're reacting in a way that
854
00:49:24.619 --> 00:49:27.969
we think is completely sensible, but it's not when you
855
00:49:28.010 --> 00:49:29.199
take one step back from it.
856
00:49:30.329 --> 00:49:30.690
Yeah.
857
00:49:30.750 --> 00:49:34.190
And I think we can hypothesize that dopamine is involved
858
00:49:34.230 --> 00:49:38.849
in this process too. Um, that, essentially when we see,
859
00:49:39.289 --> 00:49:42.030
when our opinion is validated with a large group and
860
00:49:42.070 --> 00:49:44.739
then we're experiencing an emotion at the same time that
861
00:49:44.820 --> 00:49:48.300
many other people are experiencing that emotion, that's one of
862
00:49:48.360 --> 00:49:51.360
the ways that we feel connected to other people, right?
863
00:49:51.480 --> 00:49:56.369
Sharing an emotional experience. And we know that feeling connected
864
00:49:56.409 --> 00:49:59.730
to other people releases oxytocin, which is our love hormone,
865
00:49:59.789 --> 00:50:02.989
which binds to dopamine receptors in the reward pathway, which
866
00:50:03.050 --> 00:50:05.550
then release dopamine. So we, I think there is this
867
00:50:05.610 --> 00:50:08.739
sense in which we are kind of getting high off
868
00:50:08.780 --> 00:50:12.280
of this group experience, whatever it may be, whether it's,
869
00:50:12.860 --> 00:50:16.539
you know, people watching people watching other people make music.
870
00:50:16.639 --> 00:50:18.900
Like now, you know, it's not just videos of people
871
00:50:18.940 --> 00:50:21.420
making music. We watch other people having
a reaction to
872
00:50:21.440 --> 00:50:24.440
the music and that makes it more potent because we're
873
00:50:24.480 --> 00:50:26.539
having a shared emotional experience.
874
00:50:26.780 --> 00:50:30.440
They're called reaction videos. Yeah. They're for everything. They got
875
00:50:30.460 --> 00:50:30.739
it for.
876
00:50:31.800 --> 00:50:34.920
I've even been encouraged to get, I've posted a reaction
877
00:50:34.960 --> 00:50:38.880
video to a TikTok. Just for that context. Because I
878
00:50:38.889 --> 00:50:42.179
was duly notified by someone one-third my age on our
879
00:50:42.219 --> 00:50:44.340
staff that that was a thing to do for a
880
00:50:44.380 --> 00:50:48.159
particular posting by another person who made music about the planets.
881
00:50:48.219 --> 00:50:49.619
And then I was.
882
00:50:49.559 --> 00:50:52.389
Reacting to the planets. It was cute. It was very cute.
883
00:50:52.449 --> 00:50:58.489
It was not. We weren't promoting insurrection, okay? Good to know.
884
00:50:59.369 --> 00:51:02.309
Professor, this sort of safety in numbers didn't, back in
885
00:51:02.369 --> 00:51:04.309
my day, used to call that herd mentality.
886
00:51:04.909 --> 00:51:08.619
Right, herd mentality, feeding frenzy, these types of things.
887
00:51:08.659 --> 00:51:11.340
But I mean, what's the term? Is it rageaholic?
888
00:51:12.239 --> 00:51:15.159
Yeah, rageaholic. I mean, you know, it is important to
889
00:51:15.199 --> 00:51:18.400
realize that you can get addicted not just to sort
890
00:51:18.440 --> 00:51:21.619
of positive stimuli, but actually aversive or negative. You know,
891
00:51:21.639 --> 00:51:24.119
people are doom scroll. They get addicted to the news.
892
00:51:24.199 --> 00:51:27.039
They get addicted to becoming enraged. I think that the
893
00:51:27.079 --> 00:51:31.929
addiction phenomenon could even... apply to like a domestic violence
894
00:51:31.989 --> 00:51:36.190
situation where people kind of get addicted to the uncertainty
895
00:51:36.510 --> 00:51:42.420
of that kind of, you know, violent relationship, which is
896
00:51:42.469 --> 00:51:44.860
maybe why, you know, sometimes people keep going back.
897
00:51:44.880 --> 00:51:45.500
They can't leave it.
898
00:51:45.659 --> 00:51:47.579
And what about people jump out of airplanes for fun?
899
00:51:49.150 --> 00:51:54.190
Yeah, so that's been researched to some degree. And what
900
00:51:54.210 --> 00:51:57.329
they find is that after the first jump, there's this
901
00:51:57.389 --> 00:52:02.170
kind of like paralyzed terror in the aftermath. But with
902
00:52:02.289 --> 00:52:07.690
subsequent jumps, people get just frankly euphoric. There's an enormous high.
903
00:52:08.110 --> 00:52:11.050
But also with people who jump all the time, they
904
00:52:11.090 --> 00:52:13.789
develop anhedonia, which is to say they develop a kind
905
00:52:13.809 --> 00:52:16.130
of depressed state. There's probably like a flooding of their
906
00:52:16.150 --> 00:52:18.840
brain of neurotransmitters. And then it's too much and then
907
00:52:18.860 --> 00:52:22.340
you have this kind of compensation so that it's possible
908
00:52:22.929 --> 00:52:24.630
and it's hypothesized even in the literature.
909
00:52:24.650 --> 00:52:27.650
Well, there's an answer. There's an answer to that. The
910
00:52:27.690 --> 00:52:29.530
next jump you make, just do it without the shoot.
911
00:52:30.690 --> 00:52:33.510
That's it, right? Or go higher and higher or whatever
912
00:52:33.550 --> 00:52:35.309
it is.
913
00:52:35.489 --> 00:52:39.110
Thank you, Chuck, for solving that problem for us here. Gary, Gary,
914
00:52:39.130 --> 00:52:40.010
we got to close this down.
915
00:52:40.090 --> 00:52:44.010
I know, but before we do, what's the next big addiction?
916
00:52:44.719 --> 00:52:45.599
Is he going to be AI?
917
00:52:45.780 --> 00:52:48.380
Oh my God, that sounds like the worst reality show ever.
918
00:52:49.679 --> 00:52:52.340
That's big addiction.
919
00:52:53.360 --> 00:52:57.139
Gosh, I know. I'm trying hard to prevent people from
920
00:52:57.179 --> 00:52:57.840
getting addicted to more stuff.
921
00:52:57.860 --> 00:52:59.150
But we've already seen that movie. It was called Her.
922
00:52:59.829 --> 00:53:00.690
That movie's been made.
923
00:53:01.389 --> 00:53:02.909
Yes, yes, that's right.
924
00:53:02.929 --> 00:53:09.269
Yeah, the main character's addicted to this AI woman on
925
00:53:09.289 --> 00:53:11.409
his phone. And then you see everybody around him addicted
926
00:53:11.429 --> 00:53:13.429
to their own AI lover.
927
00:53:13.619 --> 00:53:16.320
Right, their own devices, yeah.
928
00:53:16.659 --> 00:53:21.059
It's because people were left to their own devices. There
929
00:53:21.099 --> 00:53:23.659
you go. I saw what you did there.
930
00:53:23.679 --> 00:53:27.360
You saw what I did there. Listen, Anna, this has
931
00:53:27.389 --> 00:53:30.949
been a delight. On a sad topic, you shed some
932
00:53:31.030 --> 00:53:32.889
important light on it for us all.
933
00:53:32.929 --> 00:53:33.510
Great stuff.
934
00:53:33.550 --> 00:53:37.610
And it clearly doesn't or shouldn't end here. We will
935
00:53:37.769 --> 00:53:41.030
totally find another reason to bring you back on. because
936
00:53:41.090 --> 00:53:44.739
this is a never-ending challenge that we all face, if
937
00:53:44.800 --> 00:53:47.820
not for ourselves, but for loved ones or certainly for
938
00:53:47.880 --> 00:53:51.559
society at large. So thank you for your expertise there.
939
00:53:51.980 --> 00:53:54.849
And your two books, give me the names of those again.
940
00:53:54.889 --> 00:53:55.769
I love the first one.
941
00:53:55.829 --> 00:53:57.389
What was that? What's that called?
942
00:53:57.429 --> 00:53:58.190
Drug Dealer MD.
943
00:53:58.210 --> 00:54:01.409
Drug Dealer MD. Great title there. Who publishes these, by
944
00:54:01.429 --> 00:54:01.579
the way?
945
00:54:03.250 --> 00:54:06.530
The first is Johns Hopkins University Press and the Dopamine
946
00:54:06.570 --> 00:54:08.880
Nation is published by Dutton Penguin Random House.
947
00:54:08.889 --> 00:54:09.179
Wow.
948
00:54:09.239 --> 00:54:10.820
So that means it's got good distribution there.
949
00:54:10.940 --> 00:54:11.360
Okay.
950
00:54:11.480 --> 00:54:13.500
We'll look for that. All right.
951
00:54:13.800 --> 00:54:15.340
So Anna, thank you for being on StarTalk.
952
00:54:16.579 --> 00:54:18.179
You're welcome. Thank you for inviting me.
953
00:54:18.280 --> 00:54:22.699
All right. Chuck, Gary, we out. Yep. Pleasure. All right.
954
00:54:22.800 --> 00:54:26.579
This has been Neil deGrasse Tyson, your personal astrophysicist for
955
00:54:26.599 --> 00:54:30.980
StarTalk Special Edition on addiction. Until next time, as always,
956
00:54:31.000 --> 00:54:32.559
keep looking up.
