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.
