Psychedelic Microdosing: Prevalence and Subjective Effects
Open accessAbstract
Anecdotal reports suggest that the administration of sub-hallucinogenic doses of psychedelic compounds on a chronic, intermittent schedule – a practice known as psychedelic microdosing – is becoming increasingly popular among young adults due to its purported ability to reduce symptoms of depression and anxiety while improving cognitive function and promoting social interaction. Using an anonymous online survey, we collected data from 2347 people to 1) assess the prevalence of psychedelic microdosing and characterize the demographics of microdosers, 2) determine whether microdosers associate the practice with changes in mood, cognitive function, social interaction, or physiology, and 3) investigate frequent motives for discontinuing the practice. Fifty-nine percent of respondents (NT = 2183) reported familiarity with the concept of psychedelic microdosing, with 17% (383 respondents, NT = 2200) having engaged in this practice. Microdosers attributed psychedelic microdosing with improving their mood, decreasing their anxiety, and enhancing their memory, attention, and sociability. The most frequently cited reasons for quitting microdosing (NT = 243) were the risks associated with taking an illegal substance (24.28%) and the difficulty of obtaining psychedelic compounds (22.63%). Overall, our findings suggest that psychedelic microdosing is relatively common and is subjectively associated with a broad spectrum of socio-affective, cognitive, and physical outcomes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
