Hemp vs Marijuana: The Same Plant Split in Two by Politics

WEBVTT
00:01:19.920 --> 00:01:23.840
Welcome friends to episode 366.
00:01:23.840 --> 00:01:30.640
And today we're talking about hemp versus marijuana, or hemp versus cannabis.
00:01:30.640 --> 00:01:34.879
The same plant split in two by politics.
00:01:34.879 --> 00:01:45.439
I'm your host, Margaret, a certified gangier and TCI certified cannabis educator, and I believe your kitchen is the best dispensary that you'll ever have.
00:01:45.439 --> 00:01:48.159
Welcome to Bite Me, the show about edibles.
00:01:48.159 --> 00:01:56.560
Grab a snack or a drink, and let's dive in to today's really important topic.
00:01:56.560 --> 00:02:00.719
And if you are joining us for the first time today, welcome.
00:02:00.719 --> 00:02:03.840
This one's going to be a little heavier than it typically is.
00:02:03.840 --> 00:02:06.799
And if you've been here for a while, I appreciate you.
00:02:06.799 --> 00:02:08.240
Thanks for the support.
00:02:08.240 --> 00:02:09.759
Thank you for being here.
00:02:09.759 --> 00:02:16.879
And also, I didn't get any replies to the error that I made in last week's episode.
00:02:16.879 --> 00:02:19.360
But nobody seemed to catch it.
00:02:19.360 --> 00:02:22.639
I did just put a note about that in the show notes.
00:02:22.639 --> 00:02:31.680
So I mean, maybe you didn't actually read the show notes, but it was to encourage people to send me a message when they heard the little boo-boo that I made in last week's episode.
00:02:31.680 --> 00:02:36.240
I remember I s I heard it while I was editing and I decided to leave it because it didn't seem worth it to fix it.
00:02:36.240 --> 00:02:38.560
And I thought I'd just do something fun with it.
00:02:38.560 --> 00:02:44.639
Let's get into today's episode.
00:02:44.639 --> 00:03:02.159
And a fact that blows my mind that the plant sitting legally in a hemp field two miles from a farmer's house, and the plant that could still get someone arrested on the other side of the same county line can be genetically identical.
00:03:02.159 --> 00:03:05.759
Same species, sometimes the same seed stock.
00:03:05.759 --> 00:03:13.519
And what separates federally legal crop from controlled substance isn't the plant.
00:03:13.519 --> 00:03:15.199
It's a lab report.
00:03:15.199 --> 00:03:23.439
A number on a piece of paper that says whether the THC content came in under or over three-tenths of one percent.
00:03:23.439 --> 00:03:25.439
Yep.
00:03:25.439 --> 00:03:29.039
Three-tenths of one percent, that's the whole ball game.
00:03:29.039 --> 00:03:41.359
So today we're getting into how that happened, why the number is nowhere near as scientific as it sounds, what it means for anything you're making in your own kitchen, and how Canada, of all places, ended up drawing the line differently.
00:03:41.359 --> 00:03:43.520
So let's get into it, friends.
00:03:47.439 --> 00:03:52.719
Let's start with the botany, because this is where most of the confusion begins, and it takes about 90 seconds to clear up.
00:03:52.719 --> 00:04:03.199
And I have to admit, before I sat down to write out this episode, I had a lot of confusion about it myself, even though I know a lot of Americans.
00:04:03.199 --> 00:04:10.719
There's many US residents that are part of my cannabis club that listen to this show, you know, that I hear from all the time.
00:04:10.719 --> 00:04:16.240
And even with that access to people who live in the States, none of it seems very clear to me.
00:04:16.240 --> 00:04:20.399
And so I'm hoping this will help clear things up for you today, like it did for me.
00:04:20.399 --> 00:04:25.439
So hemp and marijuana are not two different plants.
00:04:25.439 --> 00:04:30.000
They're not even two different subspecies in any way that holds up botanically.
00:04:30.000 --> 00:04:33.039
Both are cannabis sativa L.
00:04:33.039 --> 00:04:34.399
Full stop.
00:04:34.399 --> 00:04:44.159
The distinction you've heard your whole life, the idea that hemp is one kind of plant and marijuana is a different kind of plant is a legal fiction dressed up to sound like science.
00:04:44.159 --> 00:04:47.279
What actually separates them is chemistry.
00:04:47.279 --> 00:04:54.159
Specifically, the percentage of delta-9 THC in the plant material measured on a dry weight basis.
00:04:54.159 --> 00:04:56.800
Below the threshold, it's hemp.
00:04:56.800 --> 00:04:59.120
Above it, it's marijuana.
00:04:59.120 --> 00:05:08.480
Same plant, same species, sometimes literally seeds from the same breeding program, just tested at different points in the plant's THC development.
00:05:08.480 --> 00:05:10.720
And where did that threshold come from?
00:05:10.720 --> 00:05:18.399
Not from a toxicologist, not from anyone studying what dose of THC actually produces a psychoactive effect.
00:05:18.399 --> 00:05:31.519
It came from a 1976 taxonomy paper by a Canadian botanist named Ernest Small, who was trying to sort fiber type cannabis from drug type cannabis for classification purposes.
00:05:31.519 --> 00:05:38.399
And if you've ever seen fiber type cannabis, it does look quite different than the drug type cannabis.
00:05:38.399 --> 00:05:44.240
He picked 0.3 as a reasonably clean dividing line for his own research categories.
00:05:44.240 --> 00:05:45.920
And that's it.
00:05:45.920 --> 00:05:54.000
I will mention that Ernest Small did receive the Order of Canada for a lot of his work in the agricultural botany sector.
00:05:54.000 --> 00:06:04.399
That's the whole origin story of the number that now determines whether a farmer goes to prison or gets a USDA subsidy, which is kind of messed up.
00:06:04.399 --> 00:06:14.240
It's akin to picking a number out of a hat and then building an entire federal enforcement apparatus around it 50 years later, which, as it turns out, is basically what happened.
00:06:14.240 --> 00:06:19.439
So here's the timeline.
00:06:19.439 --> 00:06:27.439
And I'm gonna try and keep it tight because the details could end up taking a lot more time than I would like to dedicate to this episode.
00:06:27.439 --> 00:06:30.959
But before 2018 in the US, none of this mattered.
00:06:30.959 --> 00:06:36.240
Hemp and marijuana were both fully illegal under the Controlled Substances Act.
00:06:36.240 --> 00:06:43.519
Cannabis sativa was Schedule One, no exceptions, no distinction between the plant that gets you high and the plant that makes rope.
00:06:43.519 --> 00:06:54.000
The 1937 Marijuana Tax Act had already lumped them together decades earlier, and the 1970 CSA just kept that lumping in place.
00:06:54.000 --> 00:06:59.920
And I do believe I did a history of cannabis episode a little while ago.
00:06:59.920 --> 00:07:02.879
I can link to as well, that we'll go into more detail around this.
00:07:02.879 --> 00:07:08.160
Then came the Agricultural Improvement Act of 2018, and you know it as the Farm Bill.
00:07:08.160 --> 00:07:19.920
It carved hemp, defined as cannabis, with no more than 0.3 delta 9 THC on a dry weight basis, out of the legal definition of marijuana entirely.
00:07:19.920 --> 00:07:27.199
Overnight, hemp became an agricultural commodity regulated by the USDA.
00:07:27.199 --> 00:07:31.439
No DEA registration required to grow it.
00:07:31.439 --> 00:07:35.199
Marijuana stayed exactly where it was, same plant.
00:07:35.199 --> 00:07:38.800
One side of a THC line became a farm crop.
00:07:38.800 --> 00:07:42.800
The other side stayed a felony in most of the country.
00:07:42.800 --> 00:07:45.680
Nobody in Congress was voting on pharmacology here.
00:07:45.680 --> 00:07:50.079
They were voting on whether hemp could be a legal fiber and CBD crop.
00:07:50.079 --> 00:07:59.920
And the 0.3 number was already sitting there for decades of prior hemp legislation, so it got adopted without anyone revisiting whether it made any sense.
00:07:59.920 --> 00:08:06.480
And here's the part that turned it from a bureaucratic footnote into an entire parallel industry.
00:08:06.480 --> 00:08:11.120
The farm bill's definition only capped Delta 9 THC.
00:08:11.120 --> 00:08:18.319
It didn't touch Delta 8 THC or THCA or any other cannabinoids that can also get you high.
00:08:18.319 --> 00:08:25.600
So the industry did exactly what you'd expect an industry to do when handed a loophole that had that much daylight in it.
00:08:25.600 --> 00:08:40.799
Companies started producing hemp-derived Delta VIII products and later hemp-derived THC flour that could be every bit as intoxicating as dispensary cannabis while staying technically compliant on paper.
00:08:40.799 --> 00:08:52.480
You can walk into a gas station in a state where cannabis is fully illegal and walk out with something that'll get you as high as what's sitting in a locked case at a dispensary three states over.
00:08:52.480 --> 00:08:56.720
One is a felony, the other is checkout aisle convenient.
00:08:56.720 --> 00:09:01.120
Same plant, same effect, often, wildly different legal universe.
00:09:01.120 --> 00:09:09.200
There's also a farming reality tucked inside this that doesn't get talked about often enough because that threshold isn't a hard wall.
00:09:09.200 --> 00:09:10.399
It's a testing outcome.
00:09:10.399 --> 00:09:20.240
Hemp farmers are one hot summer or one late harvest away from their crop testing over 0.3% and legally becoming marijuana.
00:09:20.240 --> 00:09:23.039
In the industry, this is called going hot.
00:09:23.039 --> 00:09:37.360
Under the current federal rule, a crop that tests between 0.3% and 1% THC gets treated as a negligent violation rather than a straight-up felony, which was a real improvement over the earlier version of the rule.
00:09:37.360 --> 00:09:43.680
It still means a farmer can do everything right and lose a season because the plant did what plants do in a warm year.
00:09:43.680 --> 00:09:45.599
That's not a hypothetical.
00:09:45.599 --> 00:09:48.480
That's a real risk sitting on real farms.
00:09:48.480 --> 00:09:58.319
And it's exactly the kind of thing I wanted a grower's actual voice on because I can explain the regulation, but I've never had a season's income riding on a THC test, personally.
00:09:58.319 --> 00:10:01.359
We're gonna hear from a grower later on in this episode.
00:10:01.359 --> 00:10:08.559
And just an update because all this is changing pretty quickly.
00:10:08.559 --> 00:10:27.680
The loophole that I just described is scheduled to close on November 12th of this year when a new federal standard swaps the old Delta 9 only threshold for a total THC measurement, one that sweeps the THCA and Delta 8 and caps finished hemp products at 0.4 milligrams of total THC per container.
00:10:27.680 --> 00:10:31.920
That would wipe out most of the hemp-derived THC products currently on the shelves.
00:10:31.920 --> 00:10:44.240
As of the day I'm recording this, the Senate bill has since passed a bill to push that deadline to December 11th for naturally derived hemp products, but it still needs to clear the house and get signed before it's actually law.
00:10:44.240 --> 00:10:48.880
Synthetic cannabinoids like converted Delta VI aren't included in that delay at all.
00:10:48.880 --> 00:10:52.480
They're still cut off November 12th, no matter what happens to the rest of the bill.
00:10:52.480 --> 00:10:55.200
By the time you're hearing this, who knows?
00:10:55.200 --> 00:10:57.119
Maybe that timeline will have moved again.
00:10:57.119 --> 00:11:00.640
But I'll try and keep the show notes updated if it does.
00:11:00.640 --> 00:11:09.599
Now let's cross the border because Canada has handled this whole situation differently, and it's worth understanding why.
00:11:09.599 --> 00:11:22.880
Canada legalized cannabis nationally in October 2018 under the Cannabis Act, and hemp was folded into that same framework from day one rather than being carved out through a separate agricultural bill.
00:11:22.880 --> 00:11:28.319
The industrial hemp regulations under the Cannabis Act define industrial hemp the same way the U.S.
00:11:28.319 --> 00:11:33.839
does on paper, 0.3% THC or less in the flowering heads and leaves.
00:11:33.839 --> 00:11:40.319
But the entire plant, hemp, and marijuana both sit under one regulator, and that's Health Canada.
00:11:40.319 --> 00:11:43.680
That single detail changes everything downstream.
00:11:43.680 --> 00:11:53.759
There's no equivalent of the farm bill loophole because there was never a moment where hemp got separated out from the same enforcement and testing regime that governs higher THC cannabis.
00:11:53.759 --> 00:12:02.079
CBD derived from hemp and CBD derived from any other cannabis variety are treated identically under Canadian law.
00:12:02.079 --> 00:12:09.920
There's no gas station THC flour market because the regulatory gap that made that possible in the US just doesn't exist north of the border.
00:12:09.920 --> 00:12:12.799
Is the Canadian system more restrictive in some ways?
00:12:12.799 --> 00:12:14.000
Honestly, yes.
00:12:14.000 --> 00:12:21.680
There's no equivalent of the sprawling, loosely regulated hemp drive THC beverage and gummy market you're seeing explode in the US right now.
00:12:21.680 --> 00:12:24.079
But it's also a lot more coherent.
00:12:24.079 --> 00:12:30.319
One plant, one regulator, one set of rules, whether you're growing for fiber or for a dispensary shelf.
00:12:30.319 --> 00:12:33.119
And I'll be honest with you, as a Canadian who's watched the U.S.
00:12:33.119 --> 00:12:46.799
hemp market from outside, there's almost something admirable about how clean the framework is, and something almost exhausting about how much simpler it would be to have that same clarity if I were building a business on either side of the border that draws the line so differently.
00:12:46.799 --> 00:12:52.240
Now, this isn't to say that legalization, recreational legalization in Canada is perfect by any means.
00:12:52.240 --> 00:13:07.359
I also did an interview a while back, maybe a year ago, a little bit longer, with a Mike De Villiers who wrote a book about the corporatization of cannabis in Canada, which I found very eye-opening, and I'll link to that in the show notes as well.
00:13:07.359 --> 00:13:12.000
The simplicity does make things much easier to follow.
00:13:12.000 --> 00:13:19.680
So why does any of this matter if you're just trying to make a batch of gummies on a Tuesday night?
00:13:19.680 --> 00:13:24.559
Because that THC source matters more than people realize when they're thinking about dose.
00:13:24.559 --> 00:13:42.640
A hemp-derived product relying on that dry weight percentage loophole can have wildly inconsistent actual milligram content from batch to batch, especially from smaller or less rigorously tested brands, because the whole compliance framework is built around a percentage, not a fixed dose.
00:13:42.640 --> 00:13:57.680
That gummy from the gas station and that gummy from a licensed dispensary might list similar THC numbers on the label and behave completely differently in your body because one of them was tested and formulated under a much tighter regulatory net than the other.
00:13:57.680 --> 00:14:04.319
This is exactly the kind of thing we we're going to be talking about in the certificate of analysis episode that I have coming up.
00:14:04.319 --> 00:14:16.160
Reading where your THC actually came from, hemp derived under a dry weight loophole versus marijuana derived under a licensed testing regime is a dosing literacy skill now.
00:14:16.160 --> 00:14:19.119
It didn't used to have to be, but now it does.
00:14:19.119 --> 00:14:28.480
So the more of this that you make yourself from cannabis you grew or sourced and tested with intention, the less any of this legal maze actually touches your life.
00:14:28.480 --> 00:14:36.160
You're not relying on a THC percentage calculated on a dry weight basis by someone trying to stay on the right side of a farm bill loophole.
00:14:36.160 --> 00:14:44.799
You know exactly what's going into your fusion, you know your kitchen is the best dispensary you'll ever have, and it's also the one place that none of this classification nonsense can follow you.
00:14:44.799 --> 00:15:01.039
So I asked a hemp cultivator to walk me through what that 0.3% line actually looks like from inside a field because I can explain the regulation, but I've never had my income riding on a THC test.
00:15:01.039 --> 00:15:03.440
So here's how she described it.
00:15:03.440 --> 00:15:11.279
In Canada, industrial hemp is grown under the industrial hemp regulations, and we hold a license from Health Canada to cultivate it.
00:15:11.279 --> 00:15:18.480
While some of the regulations overlap with or refer to the Cannabis Act, industrial hemp is its own regulated category.
00:15:18.480 --> 00:15:27.200
We are required to choose our seed from an approved list of cultivars that have been tested and verified as capable of meeting the 0.3% THC limit.
00:15:27.200 --> 00:15:33.440
That said, an approved cultivator is not a guarantee that every crop will come in under the limit.
00:15:33.440 --> 00:15:39.279
Growing conditions can affect the plant, so managing that risk is part of farming hemp for flour.
00:15:39.279 --> 00:15:45.200
We grow the plant much like cannabis plants and we watch the crop closely as it approaches maturity.
00:15:45.200 --> 00:15:55.200
In practice, we tend to harvest a little earlier, looking at the trichomes as well as things like flower density and signs that the plant is beginning to shut down or finish.
00:15:55.200 --> 00:15:58.160
Testing is another important part of the process.
00:15:58.160 --> 00:16:07.200
When the crop is approaching harvest, we take a representative sample from across the field and have the biomass tested to demonstrate compliance with the THC limit.
00:16:07.200 --> 00:16:11.119
The financial risk of going over the limit is significant.
00:16:11.119 --> 00:16:17.759
If a crop tests above the allowable THC level, it may no longer be marketable for its intended purpose.
00:16:17.759 --> 00:16:26.319
For a cultivator, that can mean losing the value of an entire crop after a season of putting land, labor, and money into producing it.
00:16:26.319 --> 00:16:33.920
So cultivar selection, watching the crop closely, harvest timing, and testing are all part of managing that risk.
00:16:33.920 --> 00:16:38.400
And I think that's an important distinction when people talk about hemp versus cannabis.
00:16:38.400 --> 00:16:40.720
Botanically, we're growing cannabis.
00:16:40.720 --> 00:16:46.319
The difference is the regulatory classification and the THC threshold we have to meet.
00:16:46.319 --> 00:16:57.200
That quote comes from Marianne, a hemp cultivator and producer, proudly and gratefully growing for whole hemp and abide brand products, and executive director of EducA Nation.
00:16:57.200 --> 00:17:10.960
At Educanation, cannabis education is treated as part of harm reduction, including helping people understand how cannabis is grown and why knowing and trusting your grower matters for quality, consistency, and what you're actually putting into your body.
00:17:10.960 --> 00:17:14.640
Big ups to Marianne for sharing this with me.
00:17:14.640 --> 00:17:24.079
Obviously, she is growing in the Canadian legal market, but the same risks that they're taking on obviously applies in the US side as well.
00:17:24.079 --> 00:17:25.839
So that's the Canadian side of this.
00:17:25.839 --> 00:17:30.720
One regulator, one clear threshold, real financial stakes if the crop tests over.
00:17:30.720 --> 00:17:36.319
On the US side, though, the story is messier because the threshold didn't hold the line the same way.
00:17:36.319 --> 00:17:47.519
And I want to bring in Max Johnson here, founder of the cannabis consultancy, Cannabis Wise Guys, who's written some of the sharpest analysis I've read on how this actually played out on the ground, which says a lot.
00:17:47.519 --> 00:17:53.359
And so Jackson has argued that the entire mess comes down to a miss uh missing definition.
00:17:53.359 --> 00:17:59.039
As he put it, quote, the real disease is a lack of definition.
00:17:59.039 --> 00:18:14.160
Smoke shops selling high THC flour and high dose edibles can point to the 0.3% Delta 9 threshold and call themselves compliant, even when what's actually being sold functionally is marijuana.
00:18:14.160 --> 00:18:25.440
Jackson's proposed fix is splitting the plant cap from the product cap so raw crops get more breathing room while finished consumer products get capped at a fixed milligram dose.
00:18:25.440 --> 00:18:28.000
And that's aimed at closing that exact gap.
00:18:28.000 --> 00:18:32.000
He's also been blunt about who let the gap get this wide.
00:18:32.000 --> 00:18:36.400
In a follow-up piece, Jackson didn't put the blame on regulators.
00:18:36.400 --> 00:18:40.720
He says, no outside force killed the hemp industry.
00:18:40.720 --> 00:18:53.360
His argument, in short, is that retailers selling jars with hundreds of milligrams of THC under a technically compliant CBD to THC ratio didn't get caught in a regulatory crackdown so much as invite one.
00:18:53.360 --> 00:18:58.559
And the legitimate wellness side of the hemp market is getting swept up in the fallout.
00:18:58.559 --> 00:19:03.200
Jackson has also written about the human cost sitting underneath all of this.
00:19:03.200 --> 00:19:06.960
And this is the piece that made me want him in this episode in the first place.
00:19:06.960 --> 00:19:18.080
He described walking into an operation that looked exactly like a licensed dispensary: glass cases, bud tenders, jars lined up like a legal shop, all of it selling hemp.
00:19:18.080 --> 00:19:25.279
Someone buys pre-rolls there, gets pulled over, and the officer smells cannabis and sees cannabis because that's what it is.
00:19:25.279 --> 00:19:28.480
Jackson's own conclusion about this scenario is blunt.
00:19:28.480 --> 00:19:31.759
He says, and what if I told you the cop was right?
00:19:31.759 --> 00:19:33.120
It is weed.
00:19:33.120 --> 00:19:43.120
He's also lived, this one personally, pulled over by federal agents in California while transporting properly labeled USDA compliant hemp from Pennsylvania.
00:19:43.120 --> 00:19:44.960
The paperwork was in order.
00:19:44.960 --> 00:19:49.360
He was charged anyway and had to fight it to get the charges dropped.
00:19:49.360 --> 00:20:03.279
His point isn't that hemp compliance is meaningless, is that the gap between what's legally compliant on paper and what a cop, a prosecutor, or a jury can actually tell apart in the field is where people are absorbing the risk that corporations created.
00:20:03.279 --> 00:20:08.160
So here's what keeps coming up when it comes to this topic.
00:20:08.160 --> 00:20:10.799
The plant didn't split itself in two.
00:20:10.799 --> 00:20:12.320
Politics did that.
00:20:12.320 --> 00:20:17.120
A botanist picked a number for his own paper in 1976.
00:20:17.120 --> 00:20:22.640
Lawmakers adopted it decades later without asking whether it made pharmacological sense.
00:20:22.640 --> 00:20:28.720
And now that number decides whether someone's crop is a felony or a federal farm subsidy.
00:20:28.720 --> 00:20:31.200
Same plant the whole time.
00:20:31.200 --> 00:20:35.920
And I don't know whether the answer is picking a side of that number and getting mad about it.
00:20:35.920 --> 00:20:41.519
I think the answer is understanding it well enough that it stops having power over how you think about this plant.
00:20:41.519 --> 00:20:45.279
Hemp and cannabis were never actually two different things.
00:20:45.279 --> 00:20:48.400
There were always one plant that got legislated into two.
00:20:48.400 --> 00:20:51.440
And that, my friends, is worth thinking about.
00:20:51.440 --> 00:21:03.200
I'm going to link to Max's articles that he shared with me in the show notes so you can check those out, and also the relevant episodes that I've done in the past around these topics.
00:21:03.200 --> 00:21:04.559
And I would love to hear from you.
00:21:04.559 --> 00:21:05.519
What do you think?
00:21:05.519 --> 00:21:17.279
Because this has got to be on a lot of people's minds, obviously, coming up later this year, because there are going to be many businesses who will not survive the closing of this loophole as it stands right now.
00:21:17.279 --> 00:21:21.279
Would lawmakers consider a simpler system like the Canadian one?
00:21:21.279 --> 00:21:23.600
I mean, that's worth an ask.
00:21:23.600 --> 00:21:26.960
So I'll leave that with you this week, my friends.
00:21:26.960 --> 00:21:29.120
I'm your host, Margaret.
00:21:29.120 --> 00:21:33.440
Till next time, stay curious and stay high.
