In a prospective web-based cohort of psychedelic users (baseline n=654), attrition at four weeks was predicted by baseline demographics (age and educational level) and personality traits (lower conscientiousness and higher extraversion), while baseline attitudes toward psychedelics and the intensity of challenging acute experiences did not predict dropout. These results align with attrition patterns seen in other longitudinal research and suggest that dropout in naturalistic psychedelic studies is unlikely to be driven by advocacy or negative drug experiences, reducing concerns about systematic bias.
