What it is about
The Afterglow-Survey is conducted by the Psychotropic Substances Research Group of the Charité Universitätsmedizin Berlin. The aim of the study is to investigate the effects of psychoactive substances that occur after the acute effects of the substance have subsided. The intake of psychoactive substances such as LSD, psilocybin, cocaine or amphetamine has various effects on consciousness. A distinction can be made between the immediate effects of the substances and the effects that first occur in the days following substance use. In the Afterglow-Survey we investigate which effects on the mood and subjective experiences occur in the days after the intake of psychoactive substances. We would like to find out how after-effects differ between the substances.
Participation in the survey is completely anonymous and no IP address will be saved. It is therefore not possible for us to trace back who completed the questionnaire.
