Recommendations for Reducing the Risk of Cannabis Use-Related Adverse Psychosis Outcomes: A Public Mental Health-Oriented Evidence Review 🔓

Journal of Dual Diagnosis

As legal controls liberalize around cannabis, the authors reviewed the literature about links between cannabis use and psychosis to make recommendations for consumers, health professionals, and policy makers to decrease risk of developing psychosis symptoms. The authors provide 11 recommendations and the level of evidence for each. Recommendations based on the most substantial evidence of linkage to psychosis include: 1) avoid use in adolescence (<16), 2) avoid cannabis with high tetrahydrocannabinol (THC) concentration, 3) limit frequency of use, 4) avoid use if experiencing psychosis symptoms or receiving treatment, and 5) avoid use if one has other risk factors for developing psychosis.
