the claim

Psychedelic use increases the risk of developing schizophrenia.

the verdict
CONTESTED PARTIAL
Recorded sources
1 source for · 4 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Psychedelic use increases the risk of developing schizophrenia?

Partly. Reference and review sources indicate that psychosis or schizophrenia from psychedelic use is rare and largely confined to those with pre-existing susceptibility, while one clinical text hedges that poly-drug use may increase psychosis risk. No retrieved item directly establishes that psychedelic use increases schizophrenia risk in the general population.
