From 2017 – 2022, law enforcement seizures across the United States of mushrooms containing psilocybin increased dramatically, according to a new study funded by the National Institute on Drug Abuse (NIDA). The number of law enforcement seizures increased from 402 seizures in 2017 to 1,396 in 2022. In addition, the total weight of psilocybin mushrooms seized by law enforcement increased from 226 kg (498 lbs.) seized in 2017 compared with 844 kg (1,861 lbs.) in 2022. This analysis, published in Drug and Alcohol Dependence, was led by researchers at New York University (NYU) Langone Health in New York City, and the University of Florida, Gainesville. The data used for the analysis were collected through the High Intensity Drug Trafficking Areas (HIDTA) program, a grant program aimed at reducing drug trafficking and misuse administered by the Office of National Drug Control Policy. Though law enforcement seizures do not necessarily reflect prevalence of use, they represent an indicator of the availability of illicit drugs. "We are in the middle of a rapidly evolving cultural, media, and legal landscape when it comes to psychedelics, and we need data to help shape informed and appropriate public health strategies," said NIDA Director Nora D. Volkow, M.D., in announcing the research publication last week. "Moving forward, we must continue to track data on the availability of psychedelics, patterns in use, and associated health effects to guide efforts in promoting accurate education and reducing potential harms among people who do plan to use psychedelic drugs." Adverse effects of psilocybin mushrooms, such as "bad trips," are marked by "distorted thinking, perceptual changes, putting oneself in physical danger, and intense feelings of fear, anxiety, and confusion," according to NIDA. "People who take psychedelic drugs like psilocybin may also experience short‐term side effects such as raised blood pressure and heart rate, agitation, confusion, vomiting, or nausea, which may be severe and require medical attention." Joseph J. Palamar, Ph.D., M.P.H., associate professor at the NYU Grossman School of Medicine, co‐investigator on the NIDA‐funded National Drug Early Warning System (NDEWS), and lead author on the paper, said "Research studies suggesting its effectiveness in treating mental health issues and extensive positive media coverage may lead some people to seek 'shrooms' outside of medical contexts. People who use psilocybin outside of medical supervision need to be educated about risks associated with use." [ABSTRACT FROM AUTHOR]
