Anecdotal: I know 4 people well enough to know that they had psychotic episodes. All of them were using cannabis at the time of onset. I don't think it caused those diseases in those people, but I think if you have schizophrenia or bipolar I, or critically if you might have it but are not yet diagnosed, it can mix poorly and you could be in for a bad time with long term consequences, so be careful. I am in favor of legalization, but people need to get less defensive about this. It's harmless for most people and shouldn't be a crime for law abiding adults. But there's real risks for that small subset of people. Also anecdotal: There were a few times where I saw mental health professionals ask in my town "how often do you use cannabis?" as one of the first screening questions, one of them said offhand that they see it a lot in their line of work.
