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.

A poll for you:

If I started a video broadcast of this newsletter on YouTube where I covered the science & top headlines each week, would you support that on Patreon?
If so, just click the heart button on this email or reply to this newsletter with a ‘yes’.

(This newsletter takes me ~2 days per week & with a new freelancing business to run, I’m working to find a balance that still keeps diapers on the baby’s butt)

New work by me:
I forgot to announce my newest science article: Glutamate, A Love Story
For ProjectCBD, the piece focuses on how the endocannabinoid system utilizes the electric glutamate neurotransmitter for so many of its functions. I previously published on serotonin & the ECS – and now I plan on continuing the series with several more neurotransmitters over the next months.

This week:
Lots on cancer, so much on pregnancy & breastfeeding that I had to break it out into its own section & an especially long & annotated section on the War on Drugs, perhaps the most important thing I’m actually doing here.

My ad: Cannabis counseling sessions for your health

Cannabis & the cannabinoids are powerful medicines. Are you – or a family member – intrigued to try them for your health but don’t know how to start?

You can see my advice here for using them for pain, neurodegeneration, autism, insomnia & anxiety/depression here. However, with the many tools out there such as CBD, THC, PEA, OEA & CBDA, personalized 1-on-1 advice can be helpful, especially for people new to cannabis.

If you want someone experienced in listening to patients to create a plan with you to help you find relief, book a 1-on-1 session with me here:

At least once a month (for the ~4 years I’ve been going through the literature like this), I find a new pathway that cannabis uses to mediate its effect. It’s wild. Most drugs use one or two major pathways to get their job done, but in that series I’m working on for ProjectCBD about the cannabinoids, I already have the first dozen pathways lined up to write about. Plus, there’s a dozen more minor ones that I could cover as well.
Quite simply, it’s a helluva plant.

An evergreen note on reading restricted paper:
First stop for seeing if there’s a free version of a paper, use the Google Scholar Chrome extension (Mac version) or Google Scholar itself.
For the infamous backdoor, use Sci-Hub – the pirated papers repository (Chrome extension here). This works better for older paper than the stuff that just came out.
For Twitter users, send a Tweet of the paper’s title with the hashtag #icanhazpdf. It works because people are beautiful(ish).
Finally, email the author. They’re almost always happy to oblige because, thanks to the predatory academic publishing system, they don’t make a dollar off of their papers.

The War on Drugs & Harm Reduction

New York had high goals for its cannabis equity program, but with no chief equity officer in place, no advisory board & no detailed plan (as required by law), it’s in danger of becoming one more hothouse of smoke & mirrors where the people most impacted by the War on Drugs are locked out
https://mjbizdaily.com/as-new-york-develops-adult-use-marijuana-rules-social-equity-concerns-emerge
They did have a helluva goal too: half of the licenses to social equity applicants & a $200 M fund to support those businesses

A California task force zeroes in on the War on Drugs & its racist enforcement as a method of social control for the oppression of Black people
https://www.marijuanamoment.net/california-task-force-highlights-racist-drug-war-policies-in-report-on-reparations-for-black-americans
As Nixon henchmen John Ehrlichman said, “You want to know what this [war on drugs] was really all about? The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people. You understand what I’m saying?
We knew we couldn’t make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin, and then criminalizing both heavily, we could disrupt those communities. We could arrest their leaders, raid their homes, break up their meetings, and vilify them night after night on the evening news.

As we often say around here, the War on Drugs is not a failure. It’s succeeding magnificently at just what it was created to do.

Bill Bennett, former White House Office of National Drug Control Policy Director under Bush I, suggests that the Uvalde shooter had psychosis from heavy marijuana use
ttps://twitter.com/justinbaragona/status/1532738615926824960
Oh man. This guy. He used to be called ‘The Canary’ because of his addiction to sunflower seeds. He also wrote a bestselling book on virtue before getting outed as a compulsive gambler. For a strong look at his Prohibitionistic career, check out Dan Baum’s classic of Drug War reportage ‘Smoke & Mirrors: The War on Drugs & the Politics of Failure.’ And what Bennett once said about abortion, black babies & crime is so abhorrent that I won’t even repeat it. You can look it up if you want.
That being said, pro-pot people are wrong to be constantly sneering at any hints of links between psychosis & heavy cannabis use. It is perhaps the most well-proven harm from the decades of Prohibition research funded by the federal government. You can see a study confirming this in the ‘Harms’ section of this newsletter almost every week. The links are not overpoweringly strong – but they are real enough for a small subset of the population. Plus, now obscure research from the ‘50s found that cannabis use led to more aggression in animal models & adolescents alike.
Similar to most drugs, cannabis brings out what’s already there. And with its ability to make fuzzy the nature of reality, it makes all of the breadcrumbing & rabbit-holing of QAnon conspiracies & 4chan racism look more like an actual pattern instead of a senseless phantasm. The ability of cannabis to open someone to radicalization makes a lot of sense. As does the idea that it leads a few users so far from reality that they see extreme violence as a viable option. In one famous historical example, the feared Sikh warriors of India were known to drink heavy amounts of bhang (cannabis in liquid form) before going into battle because it made them fearsome warriors, even able to kill a battle elephant single-handedly.
Do I like any of this? No. But let’s not kid ourselves.

During the NBA finals, New York’s Office of Cannabis Management ran an ad slamming decades of racist cannabis policy & policing – though one local affiliate refused to run it

His office also sent a letter to TikTok asking them to stop banning cannabis education advertising sponsored by government entities.

Members of the House & Senate hold a press conference about ending the blatantly racist crack/cocaine disparity
ttps://twitter.com/RepArmstrongND/status/1534647709377994753
If this one is news to you, here’s one of the clearest examples of the studied racism of the War on Drugs. The only difference pharmacologically between cocaine & crack is that crack is cocaine with some baking soda added.
But socially, white people use cocaine & Black people use crack. Famously, the 1986 Anti-Drug Abuse Act imposed penalties 100x stronger for the same amount of crack versus cocaine. Selling 5 grams of crack would hit you with the same harshness as selling 500 g of cocaine.
Under the 2010 Fair Sentencing Act, that number was reduced to 18 to 1. But it’s still a monstrous disparity. Especially when it was the CIA that supported the early explosion of the crack epidemic in Los Angeles that later spread throughout the country.

David Simon shares that his central message from his shows ‘The Wire’ & ‘We Own This City’ is that we need to end the War on Drugs
https://www.nytimes.com/2022/05/31/arts/television/david-simon-ed-burns-the-wire-anniversary.html
I consider ‘The Wire’ to be the ‘War & Peace’ of our generation. It’s the only show I’ve watched twice & I think it gives a better sense about the senseless horrors of the War on Drugs more than any of the books I’ve ever read on the subject.
(I hope to watch ‘We Own This City’ once baby Lucie starts sleeping through the night again)

A secret shopper analysis of CBD products finds THC in a few of the products labeled THC-free
Cannabidiol (CBD) product contamination: Quantitative analysis of Δ 9-tetrahydrocannabinol (Δ 9-THC) concentrations found in commercially available CBD products
https://pubmed.ncbi.nlm.nih.gov/35690015
It feels like these researchers were looking for a gotcha. They keep referring to the presence of THC as a ‘contaminant’ - which is silly. In full-spectrum hemp extracts, you’re supposed to have a little THC. That’s the point.
The only real issue of concern that they brought up is that in the 52 products labeled as “THC-free”, 10% of them had detectable levels of THC.
Word to the wise: the label “THC Free” is just opening yourself up to a lawsuit. You can safely write that THC is below detectable limits on your equipment – but if you assert “THC free”, some weaselly lawyer will use nuclear testing to find a single atom of THC & hit you with a class-action lawsuit.

Our Construction Knowledge Maven Ned Pelger opines, “Actually, what they tested was a completely different product from most the hempcrete articles you've sent me. This was earth-hemp, which would be mixing on-site clay soils with some hemp to make an adobe-like wall.
This product could make sense. I love the concept of getting all the materials from on-site or nearby (for the hemp). For someone who wants to build their own house at low material cost but high labor, this product could work. Similar to folks building adobe brick or straw bale houses. Though building codes remain a challenge.”

Pregnancy & breastfeeding

A review of the impact of cannabinoids on fertility & reproduction
Impact of cannabinoids on pregnancy, reproductive health and offspring outcomes
https://pubmed.ncbi.nlm.nih.gov/35662548
“The biological effects of cannabis are mediated by the endocannabinoid system and studies have reported the presence of cannabinoid receptors in the male and female reproductive tract, on sperm and the placenta, suggesting the endocannabinoid system plays a role in regulating reproduction. Cannabis use can impact male and female fertility and has been associated with altered reproductive hormones, menstrual cyclicity and semen parameters. Use of cannabis in males has also been associated with erectile dysfunction, abnormal spermatogenesis, and testicular atrophy. In females, cannabis use has been associated with infertility and abnormal embryo implantation and development. The main psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), can also cross the placenta and has been detected in breastmilk. Maternal cannabis use during pregnancy and lactation has been associated with adverse effects including small for gestational age infants, preterm birth, fetal neurodevelopmental consequences, and impaired offspring sociobehavioral and cognitive development.”
After watching the data these last years, I believe all of the above to be true – but not catastrophically so.

Cannabinoid Chemistry & Technology

An analysis of a positive allosteric modulator of CB1 named ZCZ011
Molecular mechanism of allosteric modulation for the cannabinoid receptor CB1
https://pubmed.ncbi.nlm.nih.gov/35637350
An allosteric modulator is one that binds to a receptor, but not in the regular binding location. It binds somewhere else on the receptor (an allosteric location). This allosteric binding changes the overall shape of the receptor & makes other molecules either more likely or less likely to bind there depending on changes. For instance, CBD is a negative allosteric modulator of CB1. When it binds to CB1, it makes THC bind there not as strongly (and protecting you from getting unpleasantly high).

PS: From Ahmad Jamal, one of the most successful small-group leaders in jazz for six decades now, comes today’s 1956 album: ‘Count ‘Em 88’.
Beginning his piano playing at the age of 3 & his formal training at the age of 7, he launched his professional career at 14. Converting to Islam in his early 20s, he recorded his first album a year later in 1951 – and then never stopped.
Trained in both the American & European style, he became known as one of the great jazz innovators & even coined a new movement called “cool jazz”. He credits his variety to growing up in the big band era, living through the bebop era & maturing through the electronic era. And so we’ll finish with perhaps his most famous recording, the Ahmad Jamal Trio live at the Pershing Lounge in 1958.

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, 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]

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 octopus 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]

Oleoylethanolamide (unfortunately, also abbreviated as OEA sometimes)
An analog of anandamide, this lipid acts via the peroxisome proliferator-activated receptor alpha (PPAR-α) receptors on the cell’s nucleus. These alter genetic transcription, a powerful method of cellular control. In animal models, oleoylethanolamide causes them to eat less food & drink less alcohol. In roundworms, it causes them to live longer. For the orphaned GPR119 receptor (a receptor that might one day be officially designated as a cannabinoid receptor), it may be the native ligand (the thing that binds to it). It’s already identified as the native ligand for hypoxia-inducible factor 3α (HIF-3α). OEA also interact with our histamines.
[Pygmy sperm whale. Not well known, a smaller cousin to the sperm whale]

Fatty acid-binding proteins (FABPs)
These transport proteins move fatty lipids such as the endocannabinoids around the body. While still mysterious, they’re thought to move anandamide between membranes as well as transporting it to be broken down by the enzyme FAAH. Several types of FABPs exist in humans. THC & CBD bind to some of them. This may explain why endocannabinoid levels tend to increase after consuming cannabinoids. As the brain ages, the levels of FABPs decrease.

Phytocannabinoids

The cannabinoids produced by the cannabis plant.

THC (delta-9-tetrahydrocannabinol or Δ9-THC)
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]

Δ8-THC (delta-8-tetrahydrocannabinol or THC8)
A more rare cannabinoid in the plant – but one with psychoactive effects. At the moment, the ability to source Δ8-THC from hemp makes it a ‘legal high’ that’s become a hot seller across the US. Of course, the usual legislative & regulatory backlashes are following. It’s been studied as a treatment for glaucoma, eye injuries & the nausea of chemotherapy. Most people describe it as a nice mellow way to get high.
[The forest species of the African elephant – smaller & more elusive]

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 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.
[a terpene/cannabinoid that travels through the air? That could only be a flying elephant]

Pharmaceutical cannabinoids

Nabiximols (ie Sativex®)
A pharmaceutical 1:1 CBD:THC spray produced by GW Pharmaceuticals. One of the first cannabinoid pharmaceuticals on the market, Sativex is an approved treatment for neuropathic pain, spasticity, overactive bladder & the symptoms of multiple sclerosis.

Epidiolex® (in the UK, Epidyolex®)
An isolated CBD formulation approved for treating the severe seizures of Dravet syndrome, Lennox-Gastaut syndrome, or tuberous sclerosis complex. Produced by GW Pharmaceuticals, the doses tend to be incredibly high – hundreds or thousands of milligrams of CBD every day in young children. But even with that, the side effects tend to only be lethargy & stomach upset.

Dronabinol (ie Marinol® and Syndros®)
A synthetic form of THC for the treatment of anorexia in AIDS patients & the nausea of chemotherapy. These tend to not be popular with patients because it’s a horse dose of THC with no modulation by the other molecules in the cannabis plant like CBD.

Nabilone (Cesamet®)
A synthetic derivative of THC approved for treating the nausea of chemotherapy patients.
