Background: Psychedelics such as lysergic acid diethylamide (LSD) and psilocybin have shown a beneficial effect on substance use disorder (SUD) symptoms. In this systematic review, we aimed to assess the efficacy and safety of psychoactive tryptamines in patients with an SUD or non-substance-related disorder (i.e., gambling disorder) in order to provide a comprehensive overview of the available...

N,N-Dimethyltryptamine (DMT) is currently being studied for its therapeutic potential in various psychiatric disorders. An understanding of its pharmacokinetics (PK) is essential to determine appropriate dose ranges in future clinical studies. We conducted a systematic literature review on the PK of DMT. Clinical studies that administered known amounts of DMT and reported PK data and/or...

Background Psychedelic-assisted therapy [e.g., with lysergic acid diethylamide (LSD)] has shown promising results as treatment for substance use disorders (SUDs). Previous systematic reviews assessing the efficacy of psilocybin in SUDs only included clinical trials conducted in the last 25 years, but they may have missed clinical trials assessing the efficacy of psilocybin that were conducted...
