Classic psychedelic drugs and their potential therapeutic effect.
Over the past decade we have witnessed a renewed scientific interest in the classic hallucinogens (psychedelic drugs). These are substances which exert their effects by an agonist action on the 5-HT2A receptors. The purpose of this paper is to provide a short review and discussion of the psychedelic drugs, their safety profile and their potential antidepressive, anxiolytic and antiaddictive effects. The article primarily focusses on the most recent clinical trials.
