On the trends in Canadian medical cannabis after 20 years
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.”

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.

In rotator cuff surgery, CBD's effect on post operative pain is unknown because of the barbarity of the journal paywall system limiting access to scientific findings

I do loathe this current system.
And if anyone wants to help me out with an academic backdoor into the journals, I recently lost my access when a friend moved on from his lab. Your support would help me greatly in sharing the potentials & the perils of cannabinoid medicine for all these readers.

PS: This week’s album is 1976’s ‘Danger’ by the Lijadu Sisters, twin sisters from Nigeria whose musical style mixed jazz, afrobeat, reggae & waka (an Islamic oriented music of the Yoruba people). They became immensely popular in Nigeria in the ‘70s & traveled the world playing with a wide array of musicians.
