Ah, correct, I see where my confusion came from before. While I think you are largely correct, your explanation might be a bit incomplete. As far as my understanding goes, these mental disorders generally have an early onset, around your early 20s, and the question of whether drugs cause them or simply speed up the timeline is unanswered. This is partly why you should abstain from drugs as long as possible - it is better to start at 25 than at 16. In other words, if you are 30, never had any mental issues and you start smoking cannabis, you are unlikely to develop schizophrenia, for example. I may be wrong with the above, and I'd love to be corrected.
