This is fear mongering disguised as “science”

A population-based retrospective cohort study of 9.8 million people in Ontario, Canada, found that people with an emergency department visit for cannabis use or cannabis-induced psychosis were at a 14.3-fold and 241.6-fold higher risk of developing a schizophrenia-spectrum disorder within 3 years than the general population, respectively.4

So another way to state this: people who are prone to mental health disorder are likely to LEARN ABOUT IT with cannabis, but it’s not causing healthy people to go crazy

Some prohibitionist jumped on this to spin it as propaganda

Some of us are more prone to mental health issues. Cannabis is a strong trigger. It is possible to go through life without triggers. THC is not something you need in your life unless prescribed for specific conditions.

I’m all for full legalisation but legal age for most substances should be simply higher because it’s way too risky and damaging before your brain fully develops, as evidenced by the this paper.

So to be clear: because some unknown small sliver of the population may have an issue with it, you want to bubble wrap all of society?

That sounds pretty conservative to me. Too much, even

[–] misk@piefed.social -2 points 2 days ago

Where are you getting your numbers on % of population at risk of psychosis and schizophrenia to call them unknown small sliver? Cannabis being harmful to people under 25 is well studied. Most neurodivergent folk are at risk and both things compound enough so that having this kind of legal age just make sense.

I consume plenty of weed myself but I’m for responsible and controlled use. I’m glad to piss off liberals and conservatives alike since I’m a leftie.
