Psilocybin, the active ingredient in magic mushrooms, is moving into the mainstream as states move toward decriminalization and public interest in its medicinal potential grows. A landmark study reports that an estimated 8 million Americans used psilocybin in 2024.
Survey Methodology and Findings
Research led by UC San Diego School of Medicine and New York University analyzed the 2024 National Survey on Drug Use and Health. The study found that 2.8% of the U.S. population—about 8 million people—had used psilocybin during the study period. This survey is one of the few to track psilocybin use in the previous 12 months rather than just lifetime use. Dr. Kevin Yang, first author and psychiatry resident at UC San Diego, noted: “Prior surveys only captured lifetime use, which tells us little about current use patterns; someone who tried psilocybin once in college a decade ago and someone using it regularly today look identical in that data. Past-year gives us a much more clinically relevant picture of who is using psilocybin right now.”
Usage Patterns and Risk Concerns
Use was most common among young adults, with survey respondents between 18 and 25 being 1.4 times more likely to use psilocybin than those in their late 30s or 40s. People who experienced a major depressive episode in the past year were significantly more likely to seek out the drug. Use of cannabis and other hallucinogens such as LSD, MDMA, and ketamine was strongly linked to psilocybin use. Dr. Yang warned: “When psilocybin is used outside of a clinical setting, the risks look very different.” Researchers emphasized the vital importance of doctors having open, non-judgmental conversations with patients about psilocybin use to provide better harm reduction advice and monitor for dangerous interactions.
