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 newsletter collects all the new cannabinoid science each week & is a free offering from my company White Whale Creations. We produce educational content for cannabis & psychedelic companies. You can see my portfolio here.

This week…

Still catching up on science from my vacation, so you’ve got a good download here including,

· A lot on cannabinoids for neurodegeneration (my advice here)

· The power of topical CBD for the skin & skin healing (science here)

· Some disturbing epidemiology studies broken out into their own section

· & in the psychedelics section, supernormal phenomena & the headtwisters

Psychedelic science for your business?
For our category ‘Psychedelics, Plant Medicines & Other Psychoactives’, I moved up its position in the newsletter because of how much people liked it. And that inspired me to make an offer:
I’m not currently doing a deep dive on the new psychedelic science that comes out every week – but I could do that for the right company.
If you know a psychedelics company who might want all of the new psychedelic science each week, shoot this newsletter their way. Or if you have a company you’d recommend that I pitch, reply to this email & let me know.

My cannabis counseling sessions for your health

Cannabis is the medicine for aging. Its use goes far back through human history & now we understand how it works because of the endocannabinoid science. But for all the research & knowledge, the practical application is still trial & error. Everyone is different & everyone finds a different set of cannabinoids that work for them. If you – or someone in your life – needs help in figuring out what works best for you, I’m here to help.

You can see my advice for using cannabinoids for pain, neurodegeneration, autism, insomnia & anxiety/depression here.

I counsel people about using medical cannabis, CBD & THC as well as the lesser known but powerful cannabinoids like PEA (immune system health) & OEA (sleep). We’ll meet to discuss what you want to fix, we’ll come up with a gameplan of what to try, I’ll help you to buy it (almost always the cost of products comes out to less than $100) & then I’ll be there to talk you through trying them out to find the best routine for you. And this includes unlimited follow-up emails.

If you want someone experienced in listening to patients & coming up with a plan to help you find relief, book a 1-on-1 session with me here:
Cannabinoid Education Sessions.

Even in this creature with just 302 neurons (specifically, the C. elegans hermaphrodite), the endocannabinoids are necessary for homeostasis, brain growth & metabolism.

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.
3 other helpful browser extensions are: Unpaywall, Open Access Button & PaperPanda
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.

A piece on the long history between telepathy & psychedelics by Shayla Love
& an article on the “impossible” supernormal phenomena that happens with psychedelics by Dr. Mona Sobhani
I’ve been doing a TikTok series about the books I’ve been reading on the supernormal (another term for the paranormal). If interested, check out (in order of release) Keel’s ‘The 8th Tower’, UFOs by an investigative journalist, the effects of consciousness on matter by the field’s grand old man Dr. Dean Radin, reincarnation by Dr. Ian Stevenson & the newest collection of essays on the scientific theories & history that might explain all this.
Though the author who started me onto the science of the supernormal is most certainly Dr. Jeffrey Kripal. I talk about one of his books here & you can see my Lex Files interview with him here.
Also, Shayla Love turned me onto the book ‘Otherworlds: Psychedelics and Exceptional Human Experience’ by David Luke. I just started it last night – but it might be the book on the subject that I’ve found so far. According to his study, half of people who have taken psychedelics experienced some kind of supernormal phenomena. And it’s well known that early researchers on DMT referred to it as telepathine.

Dual action of ketamine confines addiction liability
You don’t have to talk to harm reduction people in the UK party scene to know that ketamine is an incredibly addictive substance. Not physically, but mentally. It creates a foggy gap between you & your pain – and because it’s so easy to take & has almost no hangover effect, you can simply take moderate amounts all of the time & get away with it. Ketamine can suck people in for years & years. Personally, it’s the most addictive substance I’ve ever interacted with.
But yeah, these mice didn’t look addicted.

A study on the effects of cannabis packaging on consumer perceptions
The Impact of Cannabis Packaging Characteristics on Perceptions and Intentions
“Edible gummies were perceived as healthier … and more socially acceptable to consume … than cannabis concentrate in a medical dropper. Participants also had more interest in trying edible gummies … and trying a free sample … than trying cannabis concentrate. Cannabis packages with a helps-you-relax health claim elicited more happy … and good … feelings than cannabis packages without this claim. Minimal effects were found for visual displays of tetrahydrocannabinol content and health warnings.”

An unsurprising study of the California cannabis market finds that higher THC levels equal higher prices
Association of Tetrahydrocannabinol Content and Price in Herbal Cannabis Products Offered by Dispensaries in California: A Purview of Consumers/Patients
Also, since the presence of CBD tends to lower the amount of THC, that means lower prices for plants with even a small amount of CBD. That’s unfortunate because as Dr. Raphael Mechoulam says, he wishes all cannabis had at least a 1% CBD level just to offset and protect from the negative psychoactive effects of THC.

They promised that hemp would save the farmers. It did not. Between the onerous red tape, the stupidly low THC limits that result in whole crops being burned or plowed under & the fact that a few large farms could supply the entire country’s CBD needs, the ‘save the farmer’ angle was always a bit of a ploy.

In general, secondhand smoke is a very overblown fear that the FDA has been using in its War on Tobacco. I know tobacco smoking is bad - but you don’t need to lie & exaggerate the risks to people around the smokers. And now, the FDA is starting to focus on thirdhand smoke, which is the particulates that attach to surfaces after smoking. That seems like an especially long reach.

PS: For this week’s sacred working music, here’s something of which I’ve never quite heard the equal: Keur Moussa’ by the Monks of Senegal.

The Keur Moussa Abbey (or ‘the House of Moses’) in Senegal is a place of prayer where the monks tend fruit trees, make cheese & handcraft their renowned koras – the lute-harps of West Africa. Their music creates a new choral tradition from the wedding of Western liturgical chants with traditional African tribal music. Sung in French & Wolof, accompanied by the kora, balafon, tom-tom & flute, the brothers of Keur Moussa Abbey were the 1993 recipients of the International Albert Schweitzer Music Prize. I hope this makes a nice start for your week.

The Living Glossary

This is a running glossary of the basic cannabinoid terms. It 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 we treat the human brain like the ocean: deep, mysterious & chockablock with fish, molecules & 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]

The second endocannabinoid neurotransmitter discovered. Only 2-AG & AEA have been well studied (thousands of research papers)
[blue whale]

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 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]

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]

Diacylglycerol lipase (DAGL or DGL)
The enzyme responsible for producing 2-AG.

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]

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). It’s also worth considering for cancer treatment.
[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 interacts 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.
[whale cars]


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)

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.

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.

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.

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.

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.
