I'm a psychiatrist who works with lots of people who are homeless and mentally ill. My experience faces a strong selection bias in that I don't see the homeless people who don't have marked symptoms of mental illness. The ones who come to my attention usually have delusions and hallucinations. Beyond anecdotes, there's some reasonable and ongoing research on the topic. Methamphetamine remains far more strongly associated with psychosis than cannabis, but both anecdotes and research support that THC extracts are considerably more likely to cause psychosis than whole flowers. There also seems to be something protective about CBD, so THC extract (dabs/oil) products appear to carry more risk due to both their high THC content and the absence of CBD. People who use cannabis heavily in adolescence also have an increased risk of developing a psychotic disorder.

Interesting response. Subjectively, do you THC-linked psychosis regularly?

  Again, strong selection bias, but yes. THC stays in your system for a long time. It can take a while to figure out if the issue is a primary psychotic disorder, like Schizophrenia, that has been exacerbated by THC or if it's only drug-induced. I occasionally see cases that appear to be completely accounted for by THC, but at a far lower rate than meth-induced psychosis.

    I'm also curious, since you work in psychiatry.... Have you seen any cases of scromiting, or "Cannabinoid hyperemesis syndrome"? These articles showed up in a big online hit in mid-2022, and never seemingly referenced again. My pessimism indicated that it was likely a hit piece against cannabis, but I'd rather ask for sure than just assume some conspiracy.

      Yes, I have seen it, but just a handful of times (single digits).

      I had it multiple times as a daily smoker.
