Abstract
Psychedelics have been increasingly studied for their potential to influence mental health and well-being, yet their relationship with broader health behaviors remains underexplored. This study examined associations between lifetime psychedelic use and health-related behaviors, including substance use, dietary habits, and impulsive tendencies. Using an extensive cross-sectional online survey, we analyzed responses from 2510 US adults reporting at least one lifetime psychedelic experience. Participants retrospectively assessed changes in behaviors following psychedelic exposure. Respondents reported improvements in various health behaviors, including reduced alcohol (66 %) and tobacco (49 %) use, improved dietary habits (49 %), and decreases in impulsive behaviors (48-72 %). Those who reported more frequent psychedelic use or engagement in microdosing were more likely to endorse positive behavioral changes (p < .001). Furthermore, while some participants reported harms associated with psychedelic use, the majority perceived lasting benefits. These findings suggest that psychedelic use is associated with broad behavioral adaptations beyond mental health, including important areas such diet, and alcohol and tobacco use. Compared with those who use full doses, participants who microdosed reported a more positive behavioral profile.
