I can speak a bit about the link between psychosis and smoking dope (personal experience) Im 60 now but in 1969 I had a full scale psychotic break after smoking just a a few hits . There is the possibility that the dope had been “dusted” with PCP but I dont know for sure....those were the days.
However almost every time I smoked dope after that (I would try every few years over the next 10 years or so) I would experience a similar state which I would label “ off the charts madness”.....to the point that the last time I ever smoked (1983 I think) I was admitted for a few days into the mental ward.
Am I schizophrenic? based on my life since then I would have to say no . Its been an interesting life but not out of the ordinary.
I have no problem with people smoking dope . I dont do it however as it drives me completely out of my head.
We are all a bit different in the chemistry department and I cant smoke dope.I would bet Jared didnt help himself either by smoking dope
Then you are wise to avoid it.
