Acute Dose-dependent Effects of DMT-bolus Applications in Healthy Subjects (DMT BDR-Study) (DMT BDR)

This open-label trial (n=36) will test a variety of mixed (or escalation) doses of DMT (5-25mg) in healthy subjects. The study is unique in testing many different dosages within the same subject (versus between groups).

Trial Details

N,N-dimethyltryptamine (DMT) is a naturally-occurring psychedelic substance widely used in recreational and spiritual settings (Ayahuasca). DMT is considered a tool to induce an altered state of consciousness of interest in psychological and psychiatric research. DMT is rapidly metabolized by monoamine oxidase (MAO) A. Therefore, it is inactive when administered orally and has a very short duration of action when administered parenterally (<20 min). However, to date no clinical study has investigated dose-response effects over a broad range of different doses of DMT within the same patient. The aim of the present study is to experimentally test different intravenous DMT bolus doses over a broad dose range and investigate the related subjective and autonomic effects in order to establish a precise dose-response relationship of DMT in healthy subjects.
