A request to spread the word:
This newsletter only spreads by word of mouth – so forwarding & telling your friends goes a long way. Thank you for your help.
If you wanted to become a paid subscriber, you get no extra content, but the support would be much appreciated. These newsletters average 5k words a week & diapers aren’t free.
This newsletter is a free offering from my company White Whale Creations.
I produce educational content such as writing, newsletters & podcasts for cannabis & psychedelic companies.
It’s hard to care about cannabinoid science at this moment. After the terrible news in the US about the end of abortion rights with Roe v Wade, sitting here & typing away seems so useless. I believe this is one of the worst things I’ve witnessed in my lifetime & my heart goes out to all the women & people with uteruses who will die quickly, or slowly, because of this ruling. One organization that you can support is the National Advocates for Pregnant Women who have been long fighting against the criminalization of birth. And unfortunately, this is just the beginning as contraception & same-sex marriage have already been mentioned for being on the chopping block. So we will do what we can.
Resist, Educate & Organize.
Cannabinoids & Women:
In odd timing, I just completed a new page on the CVResearch page about hormones & female-specific conditions here:
CBD is especially helpful for balancing our hormonal changes & THC often helps with the diseases mentioned here.
[It’s hard to be gender inclusive around these subjects. Gender effects run strong in the cannabinoid field – but gender is a spectrum & the body parts involved can differ. I think the varied effects of cannabinoids match up to our varied experiences of gender in something quite beautiful. But it’s hard to write about this in science shorthand. So if anybody has any advice on gender-inclusive scientific language, I’m happy to hear it]
My lecture ‘Glutamate, GABA & the Ouroboros of the Cannabinoids’
- this Thursday, June 30th @ 11AM PST / 2PM EST:
Hosted by the Cannabis Chemistry Subdivision of the American Chemical Society (CANN), I’ll be lecturing on the uber-important neurotransmitters glutamate & GABA. The endocannabinoid system uses these two as the runners who carry out so many of its functions & help to treat so many diseases. It’ll be a mix of neuroscience & practical healthcare for conditions.
Come check it out for free & ask a nice question at the end:
Errata: drug buying
Last week, the link in my ad about how easy it is to buy drugs on the Dark Web accidentally pointed to a Smirnoff cocktail recipe when it should have pointed to an FAQ. I realized this because more of you clicked on that link than anything else in the email (yes, I can see what you click on it). So good on ya!
Buy your drugs online. Get them delivered safely & anonymously. Use a DanceSafe test kit to test for purity.
You’re in luck! It’s never been easier, simpler or safer to acquire psychoactives.
If you’ve ever been curious, there’s no excuse now. The only thing between you & the major headtwisters is a few hours of work & a little cryptocurrency.
So go forth. Enjoy the ride.
Remember, if I don’t define a term, it’s probably in the Living Glossary at the end of every email where I define all the cannabinoids & their machinery.
[plus, what kind of whale each of them would be. No nonsense]
My ad: Cannabis counseling sessions for your health
Cannabis is the medicine for aging. Its use goes far back through human history & now we understand more of how it works because of the endocannabinoid system. 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.
I counsel people about using medical cannabis, CBD, CBD Acid (guts) & the lesser known but powerful medicines like PEA (immunity) & OEA (sleep). We’ll meet to discuss what you want to fix, we’ll come up with a game plan of what to try & I’ll help you to buy it (almost always, the cost of products comes out to less than $100). After that, I’ll be there to talk you through trying them out & finding the best routine for you. You can see my advice for using cannabinoids for pain, neurodegeneration, autism, insomnia & anxiety/depression here.
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:

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 Headlines & Fav Articles
The US Supreme Court, at the urging of the Biden administration, refused to hear two cases about worker’s compensation for medical marijuana, arguing that it’s better to let Congress & the executive branch decide
That Court is having quite a week. Besides their gun ruling, they also weakened Miranda rights. And I saw a post that seemed to sum it up, it’s not that the Democrats are weak. It’s not that they’re indecisive. It’s that they’re complicit. Despite all the warnings about this abortion ruling, the only thing they had ready were the fundraising emails.
And Biden? Let Congress & the executive branch decide on cannabis? Ha!
When, despite campaign promises, he has done nothing on cannabis – nothing besides freeing a few dozen prisoners. No new laws. No executive actions. No reining in overzealous enforcement. Meanwhile, his DEA arrested over 6k this year alone
The DEA says cannabis arrests are up to a 9-year high: 5.5M plants chopped & 32% more arrests

& in a related review about policy guidelines, they recommend a "per se limit" with a quantitative THC cut-off between 3.5 and 5 ng/ml in the bloodstream to “currently be considered the most balanced [policy] choice”
Cannabis and Driving: Developing Guidelines for Safety Policies
We often talk around here about driving as one of the thorniest problems. It’s clear that very stoned drivers shouldn’t be on the roads, especially young newbies. But ‘per se limits’ aren’t the answer. With the different tolerance levels of cannabis users – especially those regularly using high doses for cancer treatments or PTSD – an arbitrary blood level THC limit does not correlate to impaired driving. People can have that much THC in their blood days after using. Arbitrary limits will become one more tool of the Drug War & will be applied in a racially malignant way.

Around here, we always go for a good corruption case because they’re always just the tip of the iceberg. New industries are notorious for higher levels of corruption – and when you have formerly illegal products coming onto the market under a host of confusing recently enacted laws with a lot of money at stake, palms get greased. And in most cases, they get away with it. When you have crimes where all of the involved parties want to keep it a secret, only the overly greedy, the unlucky or the patently stupid get caught.

A review looking for epigenetic changes caused by synthetic cannabinoids (as well as cathinones)
Epigenetic Studies for Evaluation of NPS Toxicity: Focus on Synthetic Cannabinoids and Cathinones
Isn’t it crazy that taking a drug can turn on or off the expression of your genes – and that it can be passed down to your offspring?
Epigenetics is like the revenge of Lamarck. Now mostly remembered as the failed alternative idea to Darwin’s evolution, Lamarck said creatures changed & passed those traits onto their children. Giraffes stretched their necks & passed on longer necks to their children - instead of in evolution where the giraffes who happened to have the tallest necks had more babies. Lamarckism mostly got mocked the last century.
But with epigenetics, it’s quite clear that the trauma & stress & bad habits of this life can deliver turned off genes to your kids – and probably vice versa, but there’s a lot less studies on the happy side of epigenetics. However, we must believe in a world where your acts of kindness & secret gifts of generosity do turn on good genes for your kids.

The first two make sense. I believe there are some slight negative drags from cannabis consumption during pregnancy – though not enough to ban its use. But the idea that mothers who use it will be lesser mothers, that one feels like it’s stretching it. The work of Dr. Melanie Dreher in Jamaica says otherwise. After following cannabis using mothers there for 5 years, NIDA yanked the funding for her 10-year study because all she was finding was positives & they didn’t want that.

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)
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]
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]
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.

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.

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.

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.

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]
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]
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 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.

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.

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.
A synthetic derivative of THC approved for treating the nausea of chemotherapy patients.
