Out today in Psychopharmacology: Our scoping review on recovery of repressed memories under psychedelics, spearheaded by Anne-Fiona Griesfeller and Lotte Kooman: doi.org/10.1007/s002...

Evaluating the evidence for repressed memory recovery in psychedelic contexts - Psychopharmacology

Rationale Reports of resurfaced repressed memories during psychedelic experiences have circulated for decades and still emerge today. However, the veracity of repressed memories remains debated, and the mechanisms through which psychedelics might recover alleged repressed memories are unclear. Objectives This scoping review aimed to provide an overview of the literature on repressed memory in the context of psychedelics. It examined how repressed memory was defined, which substances were predominantly discussed, which mechanisms were proposed to explain their effects, and whether these mechanisms were empirically supported. Methods A scoping review was conducted in line with PRISMA-ScR guidelines. Web of Science, PubMed, PsycINFO and Google Scholar were searched for relevant publications. Fifty-three sources met eligibility criteria. Data were charted on study design, psychedelic substance, definitions of repressed memory, results, and proposed mechanisms. Results Most publications focused on lysergic acid diethylamide (LSD) in relation to repressed memory. Few sources provided a definition of repressed memory. Proposed mechanisms on how psychedelics might influence repressed memory included psychoanalytical reductions of defensive memory blockades and neurobiological alterations of executive control. However, empirical support for these mechanisms was limited. Conclusions The included literature did not offer a coherent explanation on how psychedelics could recover repressed memories, nor consistent evidence that they did so reliably. Future work should provide clear definitions of repressed memory in the context of psychedelics, test proposed effects of psychedelics on memory and executive control across multiple psychedelic substances, include placebo-controlled designs, and account for the potential occurrence of false memories.

Reframing Psychedelic Regulation: Tools, not Treatments In this new article, we propose to regulate psychedelics as psychotherapeutic treatment tools rather than as treatments in their own right. The use of anesthetics as treatment tools in surgery is a useful analogy.

Psychedelics could play a leading role in mental health care. But if approval is rushed without necessary guardrails in place, there will be a backlash, and these drugs will be relegated to the fringes of alternative health. That would be a tragic missed opportunity. www.nytimes.com/2025/04/28/o...

New articles from the Michigan Psychedelic Center: "Tripping into Treatment: Comparing Initial and Current Motivations for Psychedelic Use" "Psychedelics and chronic pain: self-reported outcomes on changed substance use patterns and health following naturalistic psychedelic use"

Just came across this fascinating 2024 DMT study I missed - participants who were interrupted during their DMT experience (by having to give ratings) showed significantly less reduction in depressive symptoms compared to those left undisturbed. Important implications for psychedelic therapy. 🧵

Modifying Informed Consent to Help Address Functional Unmasking in Psychedelic Clinical Trials

This narrative review describes clinical trials of psychedelic or MDMA therapy and reports from the investigators on the use of modifications to informed consent in these studies.

Psychopharmacology gets lots of criticism from psychotherapy/adjacent folks. But if someone could send me therapy trials that 1. Are double-triple blind 2. Carefully document/report AEs 3. Pre-register an SAP with ITT I would appreciate. I will wait ….
