Longitudinal studies of the association between use of cannabis and later psychosis or schizophrenia were reviewed. Studies included were studies in the general population and in conscripts, using information from interviews about use of cannabis and register-based follow-up in psychiatric case-registers or in personal interviews. There was a consistent finding that use of cannabis was associated with an increased risk of later psychosis with an odds ratio of approximately 2, when adjusted for predisposition to mental illness and socio-demographic risk factors.
