Calls to poison control centers spiked throughout the U.S. for adolescents and younger adults uncovered to the hallucinogen psilocybin, based on our evaluation of information from 55 U.S. poison facilities between 2013 and 2022. The calls elevated after 2019 when psilocybin was decriminalized and legalized in a number of cities and states.
Psilocybin is a compound found in “magic mushrooms,” a well-liked leisure drug that was decriminalized for the first time by Denver, Colorado, in 2019. Decriminalizing doesn’t imply psilocybin is authorized, however it directs the police to concentrate on different crimes. Denver additionally was the primary metropolis to legalize small amounts of marijuana in 2005 and continues to push for altering drug coverage.
Magic mushrooms are authorized to buy, possess and even domesticate in simply two states: Oregon, which legalized psilocybin in 2020, and Colorado, which adopted in 2022.
We’re an emergency medicine physician and epidemiologist. A part of our job is to trace public well being dangers associated to poisons and to create efforts to forestall them. We’re each involved in regards to the enhance in calls to poison management facilities associated to psilocybin.
Why it issues
When somebody ingests magic mushrooms, psilocybin offers them a psychedelic expertise, inflicting euphoria and alterations in how they understand area and time.
Using psilocybin also can trigger psychosis, hallucinations, delusions and agitation. Within the U.S., psilocybin is designated as a Schedule 1 substance below the Controlled Substances Act, which means it has no accepted medical use and has a high potential for abuse.
Our examine demonstrates a gradual enhance in psilocybin exposures in adolescents starting in 2019. A few of these younger individuals skilled severe well being results.
This enhance in calls occurred simply as Denver voters handed a poll measure to develop into the first city to decriminalize in Could 2019.
Since then, a number of different cities, together with Detroit, Washington, D.C., and Seattle, have additionally decriminalized psilocybin. Different cities and states have laws pending.
The poison middle knowledge we utilized in our examine isn’t damaged down by state, so it’s unimaginable to know precisely the place the calls have been coming from – and whether or not they have been in cities which have decriminalized or states which have legalized magic mushrooms.


What our analysis discovered
In the course of the 10-year interval in our examine, the National Poison Data System logged 4,055 psilocybin-involved exposures amongst younger individuals ages 13 to 25.
Between 2013 and 2018, earlier than decriminalization in Denver, the variety of psilocybin-related circumstances did not change significantly amongst any age group. A considerable yearly increase in circumstances amongst 13- to 18-year-olds started in 2019 similtaneously the primary decriminalization, and amongst 19- to 25-year-olds beginning in 2020.
Simply two years later, psilocybin circumstances reported to U.S. poison facilities more than tripled amongst adolescents and more than doubled amongst younger adults, in contrast with 2018 when the drug was uniformly unlawful.
A lot of the reported circumstances – 75.3% for adolescents and 72.1% for younger adults – required medical attention, together with admissions to a hospital or psychiatric facility. The most common effects amongst these exposures included hallucinations, delusions, agitation, speedy coronary heart charge and confusion.
What different analysis is being completed
Our findings correspond with a review of more than 30 studies that demonstrates an identical rise in acute hashish poisoning amongst youngsters and adolescents starting after marijuana was legalized in 1996.
We discover this significantly alarming, for the reason that states that legalized and cities that decriminalized psilocybin don’t permit anybody below 21 to make use of it or purchase it. This implies younger persons are getting it illegally.
