Cannabinoids & the People #57: CBD for alcohol use disorder + yin & yang for heart health + gender weirdness
Hello everyone,
[Editor’s note: the newsletter will be off next week. Going in for a minor surgery under general anesthesia. Snip snip. Prayers appreciated]
Welcome to the 57th edition of Cannabinoids & the People, a weekly newsletter where I collect all the new cannabinoid science. You can check out last week’s issue here & if you haven’t subscribed yet, please do.
As always, here’s the Living Glossary of Cannabinoid Terms & at the bottom is the album of the week.
Thanks to Kelly Ebbert of Tree of Life PR for taking advantage of the Venmo donation option (@Lex-Pelger) to support this newsletter.
Searching for sources for an article on doctors, addiction & cannabis:
I’m writing an article for the American Journal of Endocannabinoid Medicine about substance abuse disorders among doctors & the potential of using cannabis to help. If you or someone you know has experience with this & would be willing to share, please reach out.
(anonymity available upon request, but on the record preferred)
This week…
- Cannabinoids for chronic neuropathic pain & MS
- CBD for alcohol use disorder, but also reproductive toxicity
- The goods & the bads of cannabis for heart health (so much info that we broke it out as a top section)
- Gender weirdness: CBD vapes only help males with inflammatory pain but vaped CBD only helped males & in another study, effects all depended on the estrous cycle
- CBD & THC for the pain of your cat’s osteoarthritis
- Cannabis as a promoter of cervical cancer according to UK public health data as well as cannabinoids potentially lowering the power of anti-cancer drugs
- For ketamine, activating your CB1 receptor may lower the anxiety
- Nerd alert! Hemopressin may activate the CB1 receptor!
- More links between the earlier the consumption of cannabis, the more likelihood of schizophrenia (listen, I don’t like it either, but I don’t trust any activist who denies it)
- “Cannabis involved pregnancies”
- A number of negative or null trial results #honestdata
- Hemp seed protein to keep your carbon steel from rusting
- Cannabinoids found in wooly umbrellas! … (sounds like Dr. Seuss, but it isn’t)
Sponsor: PlusCBD’s unparalleled product selection
I spent 3 years working full-time for PlusCBD before I launched my consulting business so I know from the inside about their commitment to making quality CBD products. But that’s not the most special thing about them. What they do better than any other company in the industry is create a wide range of products.
Nobody else has this much…
- Oils, capsules & gummies of course
- Topicals that come as balms, creams, roll-ons & special formulations for arthritis or athletes that contain menthol & camphor
- The Reserve Collection! Oils, capsules & gummies containing from 2.5 mg to 5 mg of THC per serving (I’m constantly being asked how people in non-medical can get THC-rich products & this is always what I recommend to them. Especially because it’s an easy-to-use standard serving size that’s just the right amount for people new to THC)
- Excellent pet products in a range of flavors
- THC-free CBD softgels & gummies
- 3 very special formulations with other ingredients:
- Sleep gummies: Includes 3 mg of melatonin + extract of lemon balm & magnolia bark (two old plants for inducing sleep)
- Calm gummies: Includes 5-HTP (the serotonin precursor) & L-theanine (from tea)
- Relief capsules: Includes PEA + CBDA (see the Living Glossary for why I think these are the ingredients of the future for immune health & gut health)
This is why I recommend PlusCBD to so many of the clients I consult with: they offer an array of products like no other.

Great piece of science writing on how transcranial magnetic stimulation benefits severe depression by reversing brain signal flow in the brain
https://med.stanford.edu/news/all-news/2023/05/depression-reverse-brain-signals.html
I include this because one of the wildest & most underreported (but not understudied) aspects of the endocannabinoid system is that it causes retrograde transmission.
(I’m too tired to explain retrograde transmission tonight. I think I’ll make a video on it this week…)Clinical

What do medical cannabis patients do when they are in the hospital?
How Are Patients Who Legally Use Medical Marijuana Treated When Hospitalized?
https://pubmed.ncbi.nlm.nih.gov/37125427/
“Among those respondents, only a small percentage reported that inpatients had some access to their medical marijuana: 5.8% reported that the drug was kept in the pharmacy and dispensed like other prescriptions; another 3.4% indicated that patients kept the medical marijuana in their rooms and took it, as needed. Most respondents (55.6%) reported that patients were switched to an alternative medication during their inpatient hospital stays. Almost half (49.4%) of the nurse leaders who reported that alternative medications were used, reported that opioids were substituted, and the majority reported that the marijuana was safer than the opioids.”

Predicting binding between 55 cannabinoids and 4,799 biological targets by in silico methods
https://pubmed.ncbi.nlm.nih.gov/37101313/
“From this screening, 827 cannabinoid-target binding pairs were predicted, which included 143 unique targets. Many cannabinoids sharing core structures (cannabinoid "types") had similar binding profiles, whereas most cannabinoids containing carboxylic acid groups were similar without regards to their core structure. For some of the binding predictions (43), in vitro binding data were available, and they agreed well with in silico binding data (median fourfold difference in binding concentrations). Finally, clinical adverse effects associated with 22 predicted targets were identified from an online database.”
We haven’t even started getting to the base of this plant or this system.
An evergreen note on reading restricted papers:
First stop for seeing if there’s a free version of a paper, use the Google Scholar Chrome extension (Mac version), Google Scholar itself or try ResearchGate.
Three 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.

“The most common source of participants' information on psychedelics was their own experimentation and experiences (79.52%). Most also sought information from Internet websites (61.67%), friends (61.02%), Internet discussion forums (57.08%), books (57%), and articles in peer-reviewed scientific journals (54.55%). Few sought information from their primary health care provider (4.83%). Articles published in scientific journals, psychedelic nonprofits, and researchers based in colleges or universities were the most trusted sources of psychedelic information. Government agencies and pharmaceutical companies were the least trusted.”

Creating a mouse model of cannabinoid use disorder using the synthetic cannabinoid WIN 55,212-2
A male mouse model of WIN 55,212-2 self-administration to study cannabinoid addiction
https://pubmed.ncbi.nlm.nih.gov/37050910/
In a mouse model of vulnerability to the abuse potential of drugs (their Cryab gene is deleted), they were more likely to show addiction symptoms to a synthetic cannabinoid as well as experiencing more neuroinflammation, possibly via upregulated NF-κB
Deletion of Cryab increases the vulnerability of mice to the addiction-like effects of the cannabinoid JWH-018 via upregulation of striatal NF-κB expression

Immune System & Microbials
In blood stem cells, activating the CB1 receptor made them less responsive to inflammatory stimuli, induced functional regulatory T cells & rescued macrophages (immune cells) from death via mTORC1 signaling, glycolysis & histone modulation
Cannabinoid WIN55,212-2 reprograms monocytes and macrophages to inhibit LPS-induced inflammation
https://pubmed.ncbi.nlm.nih.gov/37006243/
In mast cells (immune cells of allergic response, inflammation & pathogen defense), the little studied endocannabinoid LPI (lysophosphatidylinositol) caused changes to the cellular skeleton & movement as well as an increased production of cytokines via the CB2 & GPR55 receptors
Lysophosphatidylinositol Promotes Chemotaxis and Cytokine Synthesis in Mast Cells with Differential Participation of GPR55 and CB2 Receptors
https://pubmed.ncbi.nlm.nih.gov/37047288/
The Skin
In a mouse model of psoriasis, activating the CB2 receptors reduced skin lesions, plaque thickness, inflammation & the levels of iNOS & CB2 expression, possibly via the Keap1/Nrf2 signaling pathway
Specific Activation of CB2R Ameliorates Psoriasis-Like Skin Lesions by Inhibiting Inflammation and Oxidative Stress
https://pubmed.ncbi.nlm.nih.gov/37000322/
The Guts & Metabolism
In mice, a certain variant of their FAAH enzyme caused them to be more prone to overeating & weight gain, perhaps via an increased response to ghrelin by orexin
A genetic variant of fatty acid amide hydrolase (FAAH) exacerbates hormone-mediated orexigenic feeding in mice
https://pubmed.ncbi.nlm.nih.gov/37039453/
The Musculoskeletal System
In patients with systemic sclerosis (a hardening of the skin & organs), an activator of the CB2 receptor did not display benefits on the endpoints measured
Efficacy and Safety of Lenabasum, a Cannabinoid Type 2 Receptor Agonist, in a Phase 3 Randomized Trial in Diffuse Cutaneous Systemic Sclerosis
https://pubmed.ncbi.nlm.nih.gov/37098795/
The Genitourinary System
In patients with urinary stents, CBD oil showed no difference from placebo on pain scores or opioid usage

In a rat model of neuropathic pain from chemotherapy, the painkiller tramadol combined well with an activator of the CB1 receptor to lower pain with a lower risk of hypothermia
Interaction of the synthetic cannabinoid WIN55212 with tramadol on nociceptive thresholds and core body temperature in a chemotherapy-induced peripheral neuropathy pain model
https://pubmed.ncbi.nlm.nih.gov/37096753/
Cool Chemistry
The common CBD oxidation product CBD-hydroxyquinone (HU-331) that occurs as a contaminant in CBD isolates can get changed by light to produce a highly reactive intermediate
CBD hydroxyquinone photo-isomerises to a highly reactive intermediate
