What is the study about?
Despite the positive effects observed in clinical studies, there are also reports of challenging experiences with the use of psychedelics. This survey focuses particularly on any challenging or traumatic experiences with psychedelics, the aftermath of which continued to burden you even after the acute effects of the substance had subsided. We want to learn more about your experience with psychedelics, how you felt in the weeks and months after, and what was or wasn’t helpful in managing any lingering challenges. Please note that the study does not focus on experiences related to self-treatment of pre-existing trauma with psychedelics.
How long does participation take and what do I gain from it?
The survey will take about ~35 minutes to complete. Participation is voluntary, and you can cancel filling out the questionnaire at any time by closing your browser window. There is no direct benefit to you from participating. Your participation, through sharing your experiences, provides a significant contribution to research on psychedelic substances effects.
Is participation anonymous?
Your participation in this survey is completely anonymous and we do not store any IP addresses. At the beginning of the questionnaire, we will ask for some personal data, such as age and gender. However, with this information, it is not possible to trace who filled out the questionnaire. This study is approved by the Ethics Committee of the Institute of Psychology at Humboldt-Universität zu Berlin (Germany) (2024-07R1).
