We sought to estimate the prevalence of lifetime psilocybin use among a national sample of US adults ages 18 and older and associated demographic/substance use correlates. Pooled data from the 2015–2018 National Survey on Drug Use and Health were utilized among 168,650 individuals 18 years or older. An estimated 9.68% of individuals reported lifetime use of psilocybin. Differences were found among demographics, drug use, and sexual identity, with bisexual identification being associated with greater lifetime use. Nearly two-thirds of individuals who have ever used Lysergic acid diethylamide (LSD), methamphetamine, and/or heroin also reportedly used psilocybin. Findings from the present study can inform harm reduction efforts and behavioral health messaging.

This suggests that psychodynamic processes, for example, possible activation of emotional conflicts – can take place spontaneously – during ayahuasca intake in this particular setting. Some participants attributed symbolic meaning to the visionary content, which was more likely to take place in psychotherapeutically motivated clients. The specific setting influence as well as corresponding expectations of the participants in native wisdom could have considerable influence on experiences and interpretations, such as communication with entities as well as receiving personal teachings.
