Online Umfrage zu psychedelischen Erlebnissen ohne (unmittelbare) vorherige Einnahme - Flashbacks und persistierende Effekte nach früherem Konsum

Psychedelicflashbacksurvey.info recruits participants for an online study on psychedelic experiences that occur without (immediate) prior use of psychedelics. The survey targets reports such as reliving earlier psychedelic experiences, flashbacks that reappear after days, weeks, months, or years, psychedelic-like experiences that feel newly similar to the psychedelic state, and persistent individual psychedelic effects after the acute drug effects are clearly over. Researchers want to describe what these experiences look like, identify potential contributing factors, understand what may contribute to distress, and collect what participants perceive as helpful for dealing with psychedelic re-experiencing. Participation is voluntary, anonymous, and takes about 15-20 minutes. The study is coordinated at Humboldt-Universität zu Berlin, with ethics approval by the Institute of Psychology ethics committee (EK 2024-44-k).
