The Afterglow-Survey is an online-based survey that investigates a newly developed instrument to measure subacute effects of psychoactive substances. 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.
