Emergency Department Visits Involving Hallucinogen Use and Risk of Schizophrenia Spectrum Disorder.

JAMA psychiatry February 1, 2025 Daniel T Myran, Michael Pugliese, Jennifer Xiao et al. 23 citations

People who had an emergency department visit involving hallucinogen use were more likely to be diagnosed with a schizophrenia spectrum disorder within three years compared with the general population (3.99% vs 0.15%). After accounting for other substance use and mental health conditions, the risk remained elevated: they were about 3.5 times as likely as the general population, 4.7 times as likely as those with an alcohol-related ED visit, and 1.5 times as likely as those with a cannabis-related ED visit. The rate of hallucinogen-related ED visits rose 86% between 2013 and 2021.

Psilocybin Dispensaries and Online Health Claims in Canada

JAMA Network Open April 1, 2025 Jenna Matsukubo, Sarah Dickson, Jennifer Xiao et al. 7 citations

As of May 2024, 57 psilocybin dispensaries operated in Canada, located in 15 of 42 major cities (35.7%) and concentrated in Ontario and British Columbia. Most stores (61.4%) were part of a chain, 91.2% had an online presence, and all sold dried mushrooms, with many also offering microdosing capsules, chocolates, and gummies. 65.2% sold products mimicking popular food brands. Among stores with websites, 86.4% claimed mental health benefits such as alleviating anxiety, yet warnings about driving, pregnancy, or history of psychosis were rare (9.1%, 13.6%, and 31.8% respectively). The findings suggest a need for greater regulatory measures to protect the public.
