Psychedelic Drugs Can Prevent a Psychotic Break

I was a freshman in college when this happened I talked to him to this day about it and he you know he has diagnosed and very severe schizophrenia. He had a psychotic break during that time and it was a process that got significantly worse over the years. The incidence of schizophrenia is not higher than the general population so if these were substances that reliably induced schizophrenia we would know that by now they've been used for hundreds of years.
