Microdosing, i.e., regularly taking very small doses of psychedelic substances has become a popular trend. In this research we investigated the short and long term effects of microdosing on wellbeing, cognition and agency. We were particularly interested in the role of belief and expectation in shaping participants microdosing experiences.



We found that microdosers reported mainly positive effects but that these were more subtle than typical media accounts of microdosing.
