Psychedelics and Mental Health: A Population StudyResults: 21,967 respondents (13.4% weighted) reported lifetime psychedelic use.
There were no significant associations between lifetime use of any
psychedelics, lifetime use of specific psychedelics (LSD, psilocybin,
mescaline, peyote), or past year use of LSD and increased rate of any of
the mental health outcomes. Rather, in several cases psychedelic use
was associated with lower rate of mental health problems.
Conclusion: We did not find use of psychedelics to be an independent risk factor for mental health problems.
