Summary
AI-generated from the abstractAt least 8.4 million U.S. adults have microdosed psilocybin in their lifetime. People who used psilocybin within the past year are more likely to report microdosing the last time they used compared to those whose use was more than a year ago. However, about 15% of lifetime psilocybin users were unsure whether they microdosed the last time they used. The top motivations for self-reported microdosing are improving physical and mental health.

Abstract
At least 8.4 million US adults have microdosed psilocybin in their lifetime. Those who have used psilocybin within the past year are more likely to report microdosing the last time they used than those who have used psilocybin more than one year ago; however, approximately 15% respondents who used psilocybin in their lifetime were unsure whether they microdosed the last time they used. Improving physical and mental health are the top motivations for self-reported microdosing among US adults.
