Cannabinoids & the People #2: MORE Act + THC for TBI + CBC & BCP
Hello everyone,
Subscribe here on Substack.
This newsletter only spreads by word of mouth – so please forward it to colleagues & share to your friends & elderly relatives. If you become a paid subscriber, there’s no extra content, but your support allows me to produce more cannabinoid science content for the community.
As always, at the bottom there’s a Living Glossary of cannabinoid terms along with the weekly music recommendation.
This week, the MORE Act passed the House, 7 CBD companies were hit with FDA warning letters for COVID claims & in science news, THC protects the brain of TBI patients, psychedelics might combine well with cannabinoids for Alzheimer’s & MDMA was shown to help with the eating disorders of PTSD.
Also, I added entries for CBC & beta-caryophyllene to our Living Glossary at the newsletter’s end.
On this end, it’s fun to spread my wings as I get to do this newsletter for myself & not for a company. So I’m going to take Rob Brezny’s advice & be more like my hero Giordano Bruno:
to be as eccentrically yourself as you want to be. Such as…
The Lex Files:
I just released a bonus episode of my podcast ‘The Lex Files’ & it includes the announcement that I’m taking this podcast solo. This means that I’m looking for sponsors for Season 3 as well as beginning the search for an audio engineer/producer who can help make this show self-supporting. If that’s of interest to you or someone you know, reach out at lex@whitewhalecreations.com.
Reader’s Questions:
An obvious first section to add to this newsletter is ‘Reader’s Questions’. Send in your questions about the science – or anything else – and I’ll do my best to answer them.
Playing with Substack:
It’s time to stretch our wings & experiment with the SubStack platform. Apparently you can like & comment on newsletters. To play along & see how the comments work, just post your favorite letter. If we get lucky, it will spell out a magic word for the week.
Big Thanks!
And quite importantly, I want to thank all of the people who have already become supporting members of this newsletter for $5 a month or $50 a year. I did not expect such an initial showering of support & you should know how much it means to me & our young family.
Resources:
Lastly, as a writer myself, I want to be diligent about sharing the people & resources that make this newsletter possible. So I’ll start with Marijuana Moment. Tom Angell & Kyle Jaeger put out the absolute best daily cannabis newsletter around. If you want to stay current, you can’t beat subscribing to this newsletter & supporting Tom’s work on Patreon.
Now, here’s your news…

The US House passes the MORE Act that would legalize cannabis
https://www.forbes.com/sites/willyakowicz/2022/04/01/us-house-of-representatives-pass-federal-cannabis-legalization-bill-more-act
I won’t usually mention legislation under consideration because most bills don’t pass into law (and I doubt this one will either), but the symbolism of this happening for only the second time in history is undeniable.
Relatedly, the Congressional Budget Office finds that if the MORE Act passes, it would generate $8.1B over ten years & lead to reduced incarceration of 37,000 person-years

New Zealand is “weeding out the weed” after cannabis plants found sprouting on the grounds of Parliament
https://www.newshub.co.nz/home/new-zealand/2022/03/speaker-trevor-mallard-weeding-out-the-weed-after-suspected-cannabis-plants-sprout-on-parliament-grounds.html
This reminds me of a great scene that I never forgot from Steinbeck’s ‘Sweet Thursday’. There’s a colorful character called Joseph and Mary Rivas with a history of petty crime who loves learning about chess from Doc because it’s one of the only things at which you cannot cheat. Anyway, one of Joseph and Mary’s greatest achievements was while working as the gardener for the Plaza in Los Angeles next to the city’s main police station:
“At about this time the Los Angeles Police Department had a puzzle on its hands. Marijuana was being distributed in fairly large quantities and at a greatly reduced price. The narcotics squad conducted raid after raid without finding the source. Every vacant lot was searched from San Pedro to Eagle Rock. And then the countryside was laid out on graph paper and the search for the pointed leaves of the marijuana went on in ever-widening circles: north past Santa Barbara; east to the Colorado River; south as far as the border. The border was sealed, and it is well known that muggles [an excellent old word for weed] does not grow in the Pacific Ocean. Six months of intensive search, with the cooperation of all local officials and the state police, got absolutely nowhere. The supply continued unabated, and the narcotics squad was convinced that the pushers did not know the source.
Heaven knows how long the situation might have continued if it had not been for Mildred Bugle, thirteen, head of her class in Beginning Botany, Los Angeles High School. One Saturday afternoon she crossed the Plaza, picked some interesting leaves growing around a potted palm, and positively identified them as Cannabis Americana. [not an actual species – which means it might have been a sly joke from Steinbeck]
Joseph and Mary Rivas might have been in trouble but for the fact that the Los Angeles Police Department was in worse trouble. They could not bring him to book. How would it look if the newspapers got hold of the story that the Plaza was the source of supply? That the product had been planted and nurtured by a city employee, freshened with city water, and fed with city manure?”
Joseph and Mary was given a floater so strongly worded that it singed his eyelashes. The police even bought him a bus ticket as far as San Luis Obispo.
Doc chuckled. ‘‘You know. Mack,” he said, “you’re almost building a case for honesty.”

The IRS is reportedly increasing audits on cannabis businesses after the COVID lull
https://mjbizdaily.com/is-irs-ramping-up-marijuana-business-audits-after-covid-19-lull/
It’s especially tough on cannabis businesses because of the notorious Section 280E that doesn’t allow companies trafficking in federally illegal substances to claim normal tax deductions. It’s one more huge drag on the industry that the SAFE Banking Act is aiming to alleviate. However, there’s a great deal of opposition to SAFE because it primarily would help businesses & does nothing to end the greater harms of the War on Drugs. It frees up the money without freeing the prisoners.

An insightful new report from NORML looks at the best practices for states regulating adult-use cannabis markets
https://norml.org/blog/2022/03/29/new-norml-report-provides-policymakers-with-guidance-on-best-practices-for-regulating-adult-use-marijuana-markets/
After looking at the 18 states who have legalized, they drew these conclusions & encourage federal lawmakers to…
· Repeal federal prohibition through descheduling
· No national traffic safety limits (probably because there is no good way to test for THC intoxication & it becomes a tool for cops to target minorities)
· Provide for automatic expungement & resentencing
· Replace the very high current tax rates with more modest ones
· Do not criminalize underage possession
· Provide labeling & packaging rules
· Consider imposing national lab testing standards
· Create advertising restrictions, but not too strong
· Promote an inclusive workforce (this one is so hard to do & usually gets more thoughts & prayers than actual action)
· Preserve state medical programs (extremely important according to groups like Americans for Safe Access who sees that when states legalize, medical programs often all but disappear & patients are left out in the cold)
· No federal potency caps (these only encourage black market where people can get the strength they prefer. There are no potency caps or limits for alcohol & cannabis doesn’t need them either)
· Civil protections for parental custody, employment, housing, professional licensure & healthcare access

In a genome-wide association study (GWAS – where they track how genetic variants are linked to certain outcomes), one variant of CB1 saw a clear link between stressful life events leading to later problematic alcohol use
The cannabinoid receptor-1 gene interacts with stressful life events to increase the risk for problematic alcohol use
https://pubmed.ncbi.nlm.nih.gov/35322131/
There are a number of known variants to the machinery of your endocannabinoid system. In this case, a variant of the CB1 receptor that only differs by one amino acid leads to an alteration in how the endocannabinoids bind to it, and from there, how well you cope with stressful life events & whether they drive you to drink.
All of this sexy deterministic thinking aside, while GWAS may be the hot new tool of the last decade or so, the results must always be met with caution because we are much more than a collection of our individual variants.

A look at treating glaucoma with cannabinoids
Cannabinoids as New Drug Candidates for the Treatment of Glaucoma
https://pubmed.ncbi.nlm.nih.gov/35299275/
It’s a bit funny that they call cannabinoids new candidates for glaucoma. The first references occurred in the Egyptian papyri three thousand years ago while in the US, the first widely known medical use of cannabis was for treating glaucoma. So much so that it became a standard joke of the late-night circuit. As Conan O'Brien said, “Medical marijuana users are now lobbying for the right to carry firearms. Because no one is a better shot than a stoned old man with glaucoma.”

A nanocrystal delivery system for CBD that allows it to be injected with greater bioavailability
Enhanced Intramuscular Bioavailability of Cannabidiol Using Nanocrystals: Formulation, In Vitro Appraisal, and Pharmacokinetics
https://pubmed.ncbi.nlm.nih.gov/35288801/
There’s so much work on nano-CBD in various forms – and most of it is a waste of time. For oral delivery, yes, the bioavailability of CBD isn’t great, but that’s true for most things we take orally. With CBD, you can just take more. The plant makes it easily & cheaply. You don’t need fancy nano-liposomal-buzzword CBD. Anyway, the majority of companies don’t make nano-CBD right anyway & it just goes back to being regular CBD. But for certain conditions like epilepsy where you need huge amounts, this nanocrystal injectable form is intriguing.

An agonist is a molecule that binds to a receptor & activates it. A full agonist activates it all the way while a partial agonist causes a less strong reaction. For humans doing drug discovery, it’s easier to create full agonists that hit hard than to create partial agonists with a more nuanced response.
There’s a metaphor in there somewhere…

PS: This week’s scintillating album is ‘Natural Elements’ by Shakti. A fusion band of high-energy jazz & South Indian music, Shakti brought together an English guitarist (John McLaughlin) with famed Indian players of the violin, tabla & ghatam (Lakshminarayana Shankar, Zakir Hussain & Vikku Vinayakram respectively). Released in 1977, this album was an influential pioneer in the ‘World Music’ movement & as one reviewer stated, “It does not matter if you live in Boise, Chennai or Rio. You should try to start each day with a smile. If you need some help doing that, simply play this tune.”

The Living Glossary
Here’s a running glossary of the basic cannabinoid terms. This will also function as the legend for the ‘neural ocean’ metaphor that I’m using in my graphic novel series on the endocannabinoid system based on Moby-Dick. You can watch a lecture laying out the full idea here, but basically, we treat the human brain like the ocean: both deep, mysterious & chockablock with fish & feedback systems that we don’t understand.
Endocannabinoids are whales. Phytocannabinoids are elephants (because what is an elephant but a whale of the land). And neurons are complex underwater cities where hundreds of fish interact.
Endocannabinoids
The cannabinoids found inside all mammals & almost every other form of life besides insects
The Endocannabinoids System (ECS)
One of the most widespread signaling systems in the human body & brain - but only first discovered in the early ‘90s. Unlike most of the classical neurotransmitters, endocannabinoids are lipids, or fats. This makes them slippery, hard to study & a supremely sensitive signaling system because of the ability of cells to detect minute changes in lipid levels & act accordingly. Intimately connected to the immune system, the neuronal system & the hormonal system, as one old scientist said to me in his cups, “If you told me that the endocannabinoid system is where the body meets the soul, I’d believe you.”
Anandamide (AEA) [Our Great White Whale]
The first endocannabinoid neurotransmitter ever discovered. Widespread in the human brain & produced ‘on-demand’ when needed. Appears quickly, broken down quickly. Often called the neurotransmitter of balance.
[in our neural ocean metaphor, the sperm whale]
FAAH (fatty acid amide hydrolase)
The enzyme that breaks down anandamide & a frequent target of drug discovery for modulating the endocannabinoid system. If you inhibit the FAAH enzyme, it does less breaking down of AEA, and your AEA levels rise. More balance.
[the giant squid that slices sperm whales in half]
CB1
The first endocannabinoid receptor discovered. Mediates the psychoactivity (getting high feeling of THC). Most importantly, it’s the most widespread receptor of its class in the human brain.
[the bar in the membrane wall of the neuronal city where endocannabinoid whales meet with messenger fish to pass on their messages into the interior of the cellular city]
2-AG
The second endocannabinoid neurotransmitter discovered. Only 2-AG & AEA have been well studied (thousands of research papers)
[blue whale]
MGL (monoacylglycerol lipase - also sometimes abbreviated as MAGL)
The enzyme that breaks down 2-AG. Another frequent target of drug discovery because inhibiting MGL raises 2-AG levels
[a giant squid that eats blue whales]
CB2
The second endocannabinoid receptor discovered. Found in almost every organ of the body & closely connected to our immune system. The CB2 occurs at low levels in the brain where it responds to neural insults.
[a gay bar in the membrane wall of the neuronal city]
Palmitoylethanolamide (PEA)
An endogenous fatty acid amide whose only reason for not being labeled as a classic endocannabinoid is because it doesn’t bind to the CB1 or CB2 receptor - but it’s a hugely important neurotransmitter found in every cell of the body. A long body of work stretching back to World War 2 has found it to be an amazingly safe & effective drug for a number of things related to the immune system. Available as a dietary supplement, this is one of the best-studied cannabinoids in humans. Highly recommended.
[North Atlantic Right whale of course. Just look at that grin…]
Oleamide (OEA)
An endocannabinoid related to sleep. They discovered it by keeping cats awake for 3 days & then analyzing their spinal fluid. You can buy it on Amazon. 2 scoops helps you to sleep while 6 scoops is a very pleasant psychoactive experience (Hamilton Morris has called it his favorite way to get high - which is saying something)
[Humpback whale, because it sings hippies to sleep]
Phytocannabinoids
The cannabinoids produced by the cannabis plant.
THC (tetrahydrocannabinol)
The well-known & well-studied molecule in cannabis that gets you high - and helps in a number of other fascinating ways.
[African elephant. Powerful, unpredictable, beautiful]
CBD (cannabidiol)
The cousin of THC that does not get you high but does a lot of the heavy lifting in why hemp has been such a staple of medicine since before recorded history. In most plants outside those bred for the recreational market, CBD is the most common cannabinoid. It binds to a wide swathe of receptors outside the endocannabinoid system including three serotonin receptors, two opioid receptors, a dopamine receptor as well as glutamate & GABA (the two most widespread neurotransmitters, the basic neuronal signals for excitation & inhibition, respectively)
[Indian elephant. sweet, gentle, you can work with it]
CBC (cannabichromene)
The third most common cannabinoid in the plant, it’s not well studied in humans despite a number of intriguing preclinical studies, especially as an anti-inflammatory and for pain. Nonpsychoactive, it interferes with the breakdown of AEA & 2-AG (leading to a rise in their levels) as well as interacting with the vanilloid receptors.
[Sri Lankan elephant. Little, sweet, not as well known as it should be]
Beta-caryophyllene (BCP)
A terpene that’s also a cannabinoid.
The terpenes of cannabis give the plant its smell. Also found in oregano, black pepper, lavender & hops, beta-caryophyllene has a spicy sweet woody smell. But unique among terpenes, this one also binds to the CB2 receptor, making it a dietary cannabinoid. It shows potential for treating inflammation, pain, anxiety & seizures. The FDA has designated it to be GRAS (generally regarded as safe) & thus it can be safely used as a food additive.
