The use of classic psychedelics among adults: a Danish online survey study

Nordic Journal of Psychiatry September 29, 2022 Tobias Søgaard Juul, Mathias E. Jensen, Anders Fink‐jensen 20 citations

Among Danish adults, classic psychedelics were primarily used for therapeutic or spiritual purposes and were linked to self-reported positive lasting effects, though they were also associated with hazardous alcohol use. DMT was linked to significantly greater positive effects than LSD and psilocybin.

Single-dose psilocybin therapy for alcohol use disorder: Pharmacokinetics, feasibility, safety and efficacy in an open-label study

Journal of Psychopharmacology February 28, 2025 Dea Siggaard Stenbæk, Emil Deleuran Poulsen, Marie Katrine Klose Nielsen et al. 15 citations

A single 25 mg dose of psilocybin, a psychedelic compound, safely reduced alcohol consumption in ten adults with severe alcohol use disorder. Over 12 weeks, heavy drinking days fell by 37.5 percentage points and drinks per day dropped by 3.4. Participants also reported rapid and lasting decreases in craving and increases in self-efficacy. Peak blood levels of the drug varied widely among individuals, from 14 to 59 µg/L. The open-label, single-group design lacked a placebo control, so larger randomized trials are needed to confirm the findings.

Single-Dose Psilocybin Therapy for Alcohol Use Disorder: Pharmacokinetics, Feasibility, Safety, and Efficacy in an Open-Label Study

Research Square August 23, 2024 Mathias E. Jensen, Dea Siggaard Stenbæk, Catharina Messell et al. 1 citation

A single 25 mg dose of psilocybin, given with preparation and integration sessions, reduced alcohol consumption in ten adults with severe alcohol use disorder. Heavy drinking days dropped by 37.5 percentage points over 12 weeks, and drinks per day decreased by 3.4 units. Participants also reported rapid and lasting reductions in craving and increased self-efficacy. Blood levels of the active metabolite psilocin varied widely between individuals, peaking from 14 to 59 µg per liter. The open-label study, which lacked a placebo group, suggests that even a single psilocybin session may be safe and effective, but larger randomized controlled trials are needed.
