Psilocybin-assisted Existential, Attachment and RelationaL (PEARL) therapy for patients with advanced cancer: protocol for a multi-method feasibility trial

Pilot and Feasibility Studies October 28, 2025 Candice Richardson, Cindy Chan, Emily Macgregor et al. 1 citation

BACKGROUND: Individuals with advanced cancer often experience high levels of distress for which there are few standardized treatment approaches. Our multidisciplinary team has combined existing evidence-based approaches into Psilocybin-assisted Existential, Attachment, and RelationaL (PEARL) therapy. PEARL therapy combines elements from psilocybin-assisted psychotherapy, including preparatory...

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

Experiential Training in Psychedelic-Assisted Therapy: A Risk-Benefit Analysis.

The Hastings Center Report July 1, 2024 Daniel Rosenbaum, Crystal Hare, Emma Hapke et al. 10 citations

Well-trained, competent therapists are crucial for safe and effective psychedelic-assisted therapy (PAT). The question whether PAT training programs should require aspiring therapists to undergo their own PAT-commonly referred to as "experiential training"-has received much attention within the field. In this article, we analyze the potential benefits of experiential training in PAT by applying...

MDMA-Assisted Therapy for Severe PTSD: A Randomized, Double-Blind, Placebo-Controlled Phase 3 Study.

FOCUS: The Journal of Lifelong Learning in Psychiatry July 1, 2023 Jennifer Mitchell, Michael P. Bogenschutz, Alia Lilienstein et al. 97 citations

Post-traumatic stress disorder (PTSD) presents a major public health problem for which currently available treatments are modestly effective. We report the findings of a randomized, double-blind, placebo-controlled, multi-site phase 3 clinical trial (NCT03537014) to test the efficacy and safety of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy for the treatment of patients with...

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

Psychedelic medicine is currently undergoing a renaissance, with interest in the medical use of these compounds exploding after decades of dormancy.[1][1] This has occurred primarily under the purview of medical researchers; however, recent legal precedents in Canada have allowed some access to

Rationale: Microdosing psychedelics – the practice of consuming small, sub-hallucinogenic doses of substances such as LSD or psilocybin – is gaining attention in popular media but remains poorly characterized. Contemporary studies of psychedelic microdosing have yet to report the basic psychiatric descriptors of psychedelic microdosers. Objectives: To examine the practices and demographics of a...

Psychedelic microdosing benefits and challenges: an empirical codebook

Harm Reduction Journal July 9, 2019 Thomas Anderson, Rotem Petranker, Adam Christopher et al. 130 citations

These mixed-methods results help summarize and frame the experiences reported by an active microdosing community as high-potential avenues for future scientific research. The MDBC taxonomy reported here informs future research, leveraging participant reports to distil the highest-potential intervention targets so research funding can be efficiently allocated. Microdosing research complements...

Microdosing psychedelics: personality, mental health, and creativity differences in microdosers
