Seizures of psychedelic mushrooms across the nation by law enforcement officials have increased significantly in recent years as attitudes regarding their use have grown more permissive, according to a government-funded study released Tuesday.
Researchers found that law enforcement officials confiscated 844 kilos of mushrooms containing psilocybin in 2022, an increase of 273 percent from 2017. Psilocybin is the psychoactive component in the fungi commonly known as magic mushrooms.
Officials at the National Institute on Drug Abuse, which commissioned the study, said that the increase in seizures of magic mushroom reflected rising use of the drugs, rather than an indication that counternarcotics officials were pursuing the substances more aggressively than before.
The marketplace for magic mushrooms, which are illegal under federal law, has boomed in recent years as several clinical studies have shown that they may be effective as therapies to treat depression and other serious conditions. But many medical professionals say they worry that the hype surrounding psychedelics has moved faster than the science.
Dr. Nora Volkow, the director of the N.I.D.A, said that preliminary clinical studies had shown that psychedelics might one day become an important tool for the treatment of psychiatric disorders, including addiction to other drugs. But she said she worried that many people were self-medicating with psychedelics.
“Psychedelic drugs have been promoted as a potential cure for many health conditions without adequate research to support these claims,” Dr. Volkow said. “There are people who are very desperate for mental health care, and there are businesses that are very eager to make money by marketing substances as treatments or cures.”
