An international Delphi consensus for reporting of setting in psychedelic clinical trials.

Nature medicine June 3, 2025 Chloé Pronovost-Morgan, Kyle T. Greenway, Leor Roseman et al. 26 citations

A Delphi consensus study with 89 experts from 17 countries identified 30 extra-pharmacological variables that are important or very important for reporting the setting in psychedelic clinical trials. These variables, forming the ReSPCT guidelines, cover physical environment, dosing session procedure, therapeutic framework and protocol, and subjective experiences. The findings reveal significant ambiguities in current conceptualizations of set and setting. The guidelines provide a new standard for designing and documenting contextual factors in psychedelic research.

Longitudinal experiences of Canadians receiving compassionate access to psilocybin-assisted psychotherapy.

Scientific reports July 17, 2024 Sara de la Salle, Hannes Kettner, Julien Thibault Lévesque et al. 21 citations

A prospective longitudinal survey of eight Canadians with cancer who received legal psilocybin-assisted psychotherapy under Section 56 exemptions found significant improvements in anxiety, depression, pain, fear of COVID-19, quality of life, and spiritual well-being two weeks after the session. Attitudes toward death, medical assistance in dying, and desire for hastened death remained unchanged. Most participants found the sessions highly meaningful, though one reported a substantial decrease in well-being. These preliminary data suggest that real-world psilocybin-assisted psychotherapy can produce psychiatric benefits similar to those in clinical trials, but limited enrollment and negative experiences indicate a need for formal real-world evaluation programs.

Psilocybin mushrooms for psychological and existential distress

Canadian Family Physician November 1, 2022 Ryan Patchett-Marble, Sean O’sullivan, Sayali Tadwalkar et al. 13 citations

Psychedelic medicine is experiencing a resurgence of interest after decades of dormancy, primarily driven by medical researchers. Recent legal changes in Canada have permitted some access to these compounds, though the abstract does not specify a main finding or argument beyond describing this renaissance and legal context.
