Sponsor: PlusCBD & a commitment to quality
I’m proud to promote the CBD-rich hemp extracts of PlusCBD because I know from the inside about their commitment to quality.
They start with agricultural non-GMO hemp grown with no pesticides: only water, soil & sunlight.
Then they use the clean, safe method CO2 extraction to get out all of the terpenes, minor cannabinoids & fatty acids that go into a quality hemp extract.
And finally they test their products at least 3 times internally & once externally by third-party labs before it ever goes out the doors.
The result is an excellent CBD-rich hemp extract product that changes people’s lives. Check out their product selection here & buy some health today.
Best Of Cannabinoid Science...
Plus, Martin Lee on how all of the pieces of the plant can be medicinal
In a study of over 3500 people, they could find no way to predict the final medical doses of CBD & THC, recommending that “Clinical guidelines should maintain a highly individual approach for cannabinoid dosing”
Can we predict the treatment doses of THC and CBD and does it matter?
Love this conclusion. “There’s no way to predict your dosage. Listen to yourself, figure it out.”
In 20 elite athletes, topical CBD was well tolerated & helpful in a number of domains
Topical cannabidiol is well tolerated in individuals with a history of elite physical performance and chronic lower extremity pain
“The mostly commonly reported effects were skin dryness (43% of study completers) and skin rash (21% of study completers), which rapidly resolved. There was a significant improvement in self-reported pain levels … and pain-related disability, including family and home responsibilities, life support activities, occupational activities, recreational activities, self-care, sexual function, and social activities.”
In a survey of women with muscular pelvic pain, the cannabis users found it effective for relieving the pain while non-cannabis users said they’d be willing to try it
Cannabis use preferences in women with myofascial pelvic pain: A cross-sectional study
75% indicated a willingness to try vaginal or vulvar applications of cannabis products & I believe that this route of administration is one of the most underutilized & important methods of medical cannabis use out there.
In patients in remission from their first episode of schizophrenia, cannabis use increased the rate of relapse, but it's not clear whether that's a trigger or a consequence

Potential, Limitations and Risks of Cannabis-Derived Products in Cancer Treatment
There has always been a big debate about how paracetamol lowers pain & this literature review adds more evidence pointing to the argument that paracetamol doesn't work via the COX pathways but by the production of the cannabinoid AM404, an activator of the TRPV1 receptors (a major contributor to neuronal response to pain in the brain & dorsal horn)

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.

PS: For my music of the week, I don’t usually spend the majority of my week listening to it, but something about Jack Fascinato had me listening to him several hours a day. I first got into him because of the fun of his ‘Palm Springs Suite’ – but apparently it was the space age pop of ‘Music From A Surplus Store’ that made him an infamous darling. He also helped to arrange the music for the legendary country crossover star Tennessee Ernie Ford, including the undying hit, ‘Sixteen Tons’. And in a piece of work close to my heart, he created the music for the circus segment of the animated short, ‘Gerald McBoing-Boing’, a classic created by Dr. Seuss for neurodivergent children.
