Millions in the US report past-year psilocybin use, study finds

A new look at data from a nationally representative survey finds that more than 8 million people, roughly 2.8% of the U.S. population, reported having used psilocybin in the year prior to the survey. The data came from the 2024 National Survey on Drug Use and Health and included responses from 58,000 people in the U.S. age 12 and older.
