Acute Analgesic Effects of DMT on Experimentally Induced Pain in Healthy Participants

N,N-dimethyltryptamine (DMT) is a classical psychedelic with similar effects like LSD or psilocybin. Preliminary evidence from case series and small open-label trials suggests that psychedelics may be promising candidates for the treatment of several pain-related diseases such as chronic pain, migraine, cluster headache or phantom limb pain. However, data from rigorously conducted and randomized clinical trials are lacking. Additionally, the potential acute analgesic properties of psychedelics remain poorly characterized. Therefore, the investigators will evaluate the efficacy of DMT on different pain qualities within a model of electrically induced pain in healthy participants. The analgesic effects will be compared to racemic ketamine (active control) and placebo within a cross-over design.
