Hello everyone,

Welcome to the 56th 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.

For becoming paid subscribers of this newsletter, thanks to cannabis elevationist Becca Williams (& congrats on her recent move to Portugal) & thanks to Arnaud Dumas de Rauly, CEO of Blinc (& congrats on their recent legal win).


Also, I’m delighted to announce that my YouTube series ‘The Graphic Novels I Should Be Writing Right Now…’ has been nominated for an Academy Award. I’d like to thank my parents, my wife Claire & the literally handful of watchers who have shot this series to the stars. Thank you!


This week…

Cannabis-Induced Catatonia in a 15-Year-Old Male: A Case Report

https://pubmed.ncbi.nlm.nih.gov/37141480/

This is a rare but known side effect of cannabis. Medical reports from India 150 years ago have patients in a complete catatonic states for hours after drinking large amounts of hashish beverages. It is less common today with our lower levels of THC intake but at least a few case studies come out every year.

Preclinical

In confirmation of the entourage effect, certain cannabis terpenes synergized with THC to increase CB1 receptor activation severalfold, even at low levels

Selected cannabis terpenes synergize with THC to produce increased CB1 receptor activation

Cannabidiol Treatment Shows Therapeutic Efficacy in a Rodent Model of Social Transfer of Pain in Pair-Housed Male Mice

https://pubmed.ncbi.nlm.nih.gov/37074109/

Mice are very sympathetic creatures. They find it very distressing to live with another mouse experiencing unrelenting pain. CBD helps them to deal with it.

And if we’re lucky, CBD will keep them passive enough to not start a revolution that overthrows the humans & their evil biomedical experiments in order to begin a murine utopia where rats & mice can finally live in peace.


The antidepressant effects of transcranial magnetic stimulation may be caused by its modulation of the endocannabinoid system as well as GABA & glutamate (the primary inhibitory & excitatory neurotransmitters of the brain, heavily involved with the endocannabinoids)

High-frequency repetitive transcranial magnetic stimulation regulates neural oscillations of the hippocampus and prefrontal cortex in mice by modulating endocannabinoid signalling

https://pubmed.ncbi.nlm.nih.gov/36965621/


In a mouse model of osteoporosis, CBD enhanced bone metabolism as well as bone healing after a break

The inhibitory effect of cannabidiol on the rewarding properties of methamphetamine in part mediates by interacting with the hippocampal D1-like dopamine receptors

https://pubmed.ncbi.nlm.nih.gov/37100273/


Against cigarette smoke, computer modeling shows the compounds of cannabis to be anti-inflammatory

Molecular Docking of the Cannabis sativa L. Bioactive Compound Against Inflammation Induced by Cigarette Smoke Exposure

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.

Lessons from 20 years of medical cannabis use in Canada

https://pubmed.ncbi.nlm.nih.gov/36952564/

“In 2001, the Canadian government granted access to those with physician-documented evidence of a severe health problem that could not be managed using conventional therapies. Most patients accessed cannabis grown under a personal production license. By 2013, authorized daily cannabis dosages were very high. In 2014, the government, concerned over illegal diversion, required that cannabis be purchased from a licensed commercial grower; personal production was banned. Physicians were given responsibility for authorizing patient access. To fill the regulatory void, the physician regulatory bodies in Canada imposed their own prescribing restrictions. After these changes, the number of physicians who were willing to support patient cannabis use markedly decline but the number of patients participating in the program sharply increased. Medical cannabis use varied by province-rates were generally lower in provinces with stricter regulations on physician cannabis prescribing. Most varieties of cannabis oil available for sale are now high in CBD and low in THC. Dry cannabis varieties, conversely, tend to be high in THC and low in CBD. Inflation adjusted prices of most varieties of medical cannabis have declined over time. We find that rates of daily cannabis use (medical or otherwise) increased markedly after the 2014 policy regime. The fraction of Canadians using cannabis daily increased again after the 2018 legalization of recreational cannabis; at the same time, participation in the medical access program declined.”

In 18 young patients with epilepsy, they showed no benefit from dispensary CBD because their blood levels did not reach the therapeutic range

Dispensary Cannabidiol (CBD): Nothing to Worry About!

https://pubmed.ncbi.nlm.nih.gov/37101430/

This paper feels like it has quite a negative bias. They dismiss any anecdotal reports of the effectiveness of dispensary CBD as being the result of prescription anti-seizure medications. This tiny study doesn’t compare to the large number of parents reporting improvements for their kids, enough so that it caused a migration of families to legal states in the early days of legalization.


A model of neurons & their supporting astrocytes looks at the negative & positive effects of CBD

Neutralization of Cannabidiol Neurotoxicity in Neuron-Astrocyte Sandwich Coculture

https://pubmed.ncbi.nlm.nih.gov/37080943/

“CBD (15 and 30 µm) causes the viability decrease, along with morphological damage, in the neuron-alone culture, whereas its neurotoxic effects are significantly attenuated by the supports of astrocytes in the neuron-astrocyte coculture. In addition, it is found that CBD-induced increase of intracellular Ca2+ concentration and depolarization of mitochondrial membrane potential, via activation of transient receptor potential vanilloid 1, are noticeably ameliorated by coculturing neurons with astrocytes.”
