This research review examined whether people with schizophrenia can safely participate in psychedelic-assisted therapy treatments. Researchers analyzed 131 studies and found that psychedelics rarely cause new psychosis in the general population (0.002%), though the risk is slightly higher in people with existing schizophrenia (3.8%). While the immediate risk appears manageable, about 13% of people who develop psychosis from psychedelics go on to develop schizophrenia, suggesting caution is still needed.
