I don’t agree with legalization, and I don’t think any drug is totally innocuous. That said, I would have to see the data. It could certainly be that people with psychosis are more likely to start smoking marijuana, instead of a causation relationship. However, if it did contribute, it wouldn’t surprise me in the least.

It could certainly be that people with psychosis are more likely to start smoking marijuana, instead of a causation relationship.

I'd also like to see a comparison with alcohol. I could easily imagine that "people who drank alcohol on a daily basis were three times more likely to be diagnosed with psychosis compared with people who never drank."
