I suspect so. My Father was only observing what he saw. He wasn't researching the cause.

The key take away for me was that he was working with young people. I suspect these people may have ended up in mental health care but much later in life.

If this were true you'd expect less of the later in life diagnoses to be drug related. I have no data on that.

That might be what parent is assuming. My view is that (a) they're already mentally ill; and (b) the psychedelic can trigger severe episodes that wouldn't otherwise have happened.

I don't know how cannabis works for people with bipolar. Laing used to interpret all psychotic disorders as the same thing. I'm not sure that's right. It seems to me that the different types of bipolar are suffficiently distinct that it's unsafe to declare them variants of the same condition. And I'm pretty sure they're not on a continuum with schizophrenia.

I don't know; I'm neither a doctor nor a therapist. It's just that a surprising proportion of the people I've known well have turned out to have some kind of psychotic disorder. Perhaps they're attracted to me, or me to them. Either way, perhaps I could be used as a kind of diagnostic sign.

I think that's a safe assumption. Things like schizophrenia and bipolar disorder tend to get worse with time.
