Heavy cannabis users have been found to have nearly four times the odds of developing schizophrenia or psychosis compared to non-users, according to a Kings College Meta-Analysis (pmc.ncbi.nlm.nih.gov)

I only skimmed the article, but I couldn't find if it was a lifelong risk of any user or rather those who were already predisposed to psychosis could bring it on with cannabis use. Anyone can trigger psychosis with stimulants like cocaine or methamphetamine.

My questions is, is this a general risk for everyone, or only those with existing risk factors? It talks about use earlier in life making it more likely to trigger negative outcomes, but assuming you are already past the presentation stage of most psychiatric disorders, would it then be safe?

I think there's an obvious case to be made that developing brains should be shielded from substance use, regardless of it's safety in adult populations or not.

On a personal note, I swear it calms my brain down. It stops the obsessive thoughts and makes the world softer and less painful.

It used to be like that for me, but I've been in various levels of anxious and ruminating for a decade and weed just cranks it up anymore.

One time I took a modest edible and it caused an intense dysphoria in the sense that I wanted to unscrew my brain and roll it across the room to not deal with it anymore. It's a bit disappointing when psychedelic visuals were once my only real source of inspiration and now I'm entirely sober.

Cool anecdote.

Thanks, I wrote it myself to relate to someone's personal note.

It's neither. It's just a correlation.

I think there’s an obvious case to be made that developing brains should be shielded from substance use,

It's not obvious. It's completely vague, condescending, and oppressive to kids. Literally everything is a "substance".

Consequences of adolescent drug use

Adolescence is a period of critical development in the brain and body. Developmental changes in the brain lead to adolescents exhibiting heightened impulsiveness, which can lead to risky behaviors that may have long-term consequences [1, 2]. In particular, the use of both licit and illicit substances in adolescence can produce both acute and enduring effects on brain function and behavior. Of great concern is the fact that the prevalence of substance use disorders as an adult is greater if substance use is initiated during adolescence [3], however, other issues can persist into adulthood both related and unrelated to continued use. Alcohol, cannabis, and nicotine are among the most commonly used substances in adolescents, in part due to their availability, perceived lack of risk, and use in social settings [4].

I'm not a buzzkill, the science of how we grow is, sorry.

why are weed smokers so committed to the "it's not even bad for you, actually it's good for you" bit, I never see alcoholics and smokers doing this
