Wojciech Osika

Wojciech Osika is an epidemiologist and psychiatric researcher whose recent work interrogates the population-level correlates and potential health consequences of classic psychedelic use. His research portfolio, as reflected in multiple collaborative manuscripts and trials, spans epidemiological analyses of lifetime psychedelic exposure and cardiometabolic outcomes (including hypertension), exploration of links between adolescent psychedelic use and psychotic or manic symptoms, and studies of behavioural correlates such as current meditation practice and alternative belief systems among psychedelic users. Osika applies cross-sectional and registry-based approaches to clarify risk–benefit patterns relevant to public health and clinical guidance.

Across these projects, Osika has emphasised rigorous assessment of psychiatric outcomes and cardiometabolic markers in large samples, contributing to the emerging literature that seeks to contextualise psychedelic use beyond individual clinical trials. His work informs harm-reduction discourse and highlights areas requiring longitudinal and mechanistic follow-up, such as the interplay between psychedelic exposure, mental-health vulnerability (e.g., bipolar disorder or psychosis risk) and cardiovascular risk profiles.
