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, research on CBDV for the severe seizures of Rett syndrome, CBD for autism & joint pain as well as combining CBD with an antibiotic to kill a drug-resistant bacteria stalking hospitals.

Also, you can follow me on Twitter (@LexPelger) for funnier takes on the science below – such as how honeybees aren’t the only ones we should be dosing

Additions & reorderings:

To the Living Glossary at the bottom, I added an entry on CBDV. Also, in addition to the usual breakout for Cancer, there’s a special section on the Heart below because some cardiology journal decided to have a special issue.
Lastly, I’m experimenting with a new section called ‘Harms & No Help’ to list the studies where cannabinoids did not work or caused harm. For researchers used to seeing all the glowing reports, I think it will be nice to get a bracing dose of the negatives.
For instance, I bet that once you've seen enough times of Jesus feeding thousands with just two fish & a loaf of bread, you eventually hope that he'll take a swing at a heckler just to break up the monotony. In the same way, after watching endless miracles with cannabis, it's nice to see that it’s not an Immaculate Plant that heals all ills & causes no harms. Though it would probably still throw all of the moneychangers out of the Temple…

I am quite surprised by how poor Substack is at handling formatting since its very purpose is newsletters (I don’t even keep my drafts in Substack anymore because I lost a third of my first newsletter to the void). So I’m constantly tinkering with the formatting on here to make it look more readable for mobile, email & web viewing. If you experience problems, please let me know so I can try to address them.

Now, here’s your news…

On autism, a review of the clinical evidence shows that the cannabinoids, and especially CBD, can help with common comorbidities as well as the central symptoms
Clinical Data on Canabinoids: Translational Research in the Treatment of Autism Spectrum Disorders
I have two cousins whose lives were changed by CBD. It’s one of first reasons that turned me into a big believer. While this review stresses that more practical translational data is needed – which is true – there’s more than enough anecdotal evidence in the online communities of parents that will help anyone seeking to get started.

& according to a federal judge, Amazon is allowed to drug screen workers in its warehouse
These last two make a bit more sense for safety reasons – except for the fact that a positive test for THC does not mean intoxication. It just means that you have ingested it within the last month, not that you’re feeling any effects right now.
This is one of the toughest parts about drug testing. For certain industries, you obviously shouldn’t be intoxicated while operating the heavy machinery – but unlike with alcohol, there’s no good way [yet] to test for THC intoxication.

The Plant & the History

The rules for using hempcrete in houses got preliminary approval from the International Code Council
As for the analysis from our Resident Construction Expert Ned Pelger, he says,
“Well that was an interesting read. I finally got some real data on [hempcrete] and can't imagine why anyone would use it as a building material:
1. No structural value
2. Corrodes metals, so any metals in contact need to be coated
3. Per above, all wiring needs to be in conduits, quite expensive add for residential construction
4. R value [measure of insulation] is poor, less than half that of fiberglass batt and one quarter that of foam. So walls need to be 2 times to 4 times thicker, a huge cost and loss of space.”

For the sound absorption of natural fibers, hemp was the clear winner

The Link Between Cannabis Use and Violent Behavior in the Early Phase of Psychosis: The Potential Role of Impulsivity
This is another idea that nobody likes & that goes against the peace & love vibe of weed, but there’s plenty of stories of people getting high & getting violent. In the ‘50s, it was a whole thing to smoke some reefer & go out, get crazy & get into fights. If everybody told you that marihuana would make you violent, that would certainly help to make it true.
A side note is that the historian Ernest Abel collected mouse studies from the ‘50s where hungry mice would get more violent if given THC. No other drug caused this reaction.

For people with cancer, a review of the efficacy of cannabis for their appetite
Efficacy of medicinal cannabis for appetite-related symptoms in people with cancer: A systematic review
The classic story in this field is that of Dr. Lester Grinspoon. A respected scientist tasked by the government to look for the harms of cannabis, he couldn’t find much. And then when his own son developed cancer, the treatments caused extreme nausea. In fact, once when his son saw his nurse in the supermarket, the association caused him to throw up immediately. But then one session, the medical team noticed that his son experienced no nausea & even asked for a sandwich after the treatment. It turns out that Dr. Grinspoon allowed his son to ingest cannabis right before tntering the hospital that day & it changed everything for him. This led to Dr. Grinspoon writing the book ‘Marihuana Reconsidered’, perhaps the most influential early cannabis tome to de-demonize the plant & to allow for the increased acceptance of cannabis as a medicine.
(Now you can follow along with the work of his son Peter who is a great voice online about cannabis as well as harm reduction. My interview with him about his own struggles with addiction was the Season 1 Finale of the Lex Files –(video here). Also, his book ‘Free Refills’ is excellent)

There’s much hay made about CBD’s potential drug interactions, and while it does interact with a number of isozymes of the CYP-450s (important liver enzymes that both activates some of the drugs we take as well clearing some of them from the body), the only clinical reports of drug-drug interactions with CBD are for warfarin. (Even then, all it does is make your warfarin ~30% stronger). As one doc I know said, ‘Warfarin is crazy. It interacts with everything.” And as Dr. Jamie Corroon says, “I don’t start to worry about drug interactions and CBD unless I’m recommending more than 100 mg per day. And even then, the evidence suggests the dose threshold for risk is much higher, closer to 1,000 mg per day.”

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.


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, endocannabinoid 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]

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]

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]

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]

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]

CBDV (cannabidivarin)

CBDV is like CBD with a shortened tail (side chain). Also nonpsychoactive, it tends to occur at low levels in most cannabis cultivars. It’s known to be an anticonvulsant & is suggested for treating autism in humans & in animal models. The cannabinoid pharmaceutical company GW has it in their developmental pipeline as GWP42006.

[An Asian elephant with a short trunk]

Beta-caryophyllene (BCP)
A terpene that’s also a cannabinoid.
The terpenes of cannabis give the plant it’s 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 a 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.
