A century of research on psychedelics: A scientometric analysis on trends and knowledge maps of hallucinogens, entactogens, entheogens and dissociative drugs.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology November 1, 2022 Marco Solmi, Chaomei Chen, Charles Daure et al. 55 citations

Over the past century, clinical research on psychedelics has evolved from an early focus on safety into a 'psychedelic renaissance' after the 1990s. A scientometric analysis of 31,687 documents from the Web of Science identified major research themes: hallucinogens/entheogens, entactogens, novel psychoactive substances (NPS), and dissociative substances. The field has shifted from basic science to clinical applications, including phase 2 and 3 trials and evidence synthesis. Recent trends include NPS, ketamine-associated brain changes, and ayahuasca-assisted psychotherapy. The USA and Canada lead in productivity, reflecting legislative influences. This translational evolution has already led to esketamine approval for depression and may lead to further approvals across mental and physical conditions. Toxicology screening tools for NPS are urgently needed and may follow a similar path.

Top Ten Tips Palliative Care Clinicians Should Know About Psychedelic-Assisted Therapy in the Context of Serious Illness.

Journal of palliative medicine August 1, 2022 William E Rosa, Zachary Sager, Megan Miller et al. 49 citations

Psychedelic-assisted therapy (PAT) is a promising treatment for conditions like treatment-resistant depression, substance use disorder, and PTSD. In palliative care, a single PAT session can produce lasting reductions in anxiety, depression, and demoralization—symptoms that harm quality of life for seriously ill and end-of-life patients. Although interest in psychedelics has revived, few resources exist for applying PAT in hospice and palliative care. This article provides 10 evidence-informed tips for palliative care clinicians, developed with international experts, to help familiarize teams with PAT, address legal and logistical barriers, discuss therapeutic competencies, and highlight approaches to maximize safety and benefits for patients and caregivers.

Psychedelic-assisted therapy for treating anxiety, depression, and existential distress in people with life-threatening diseases

Cochrane Database of Systematic Reviews September 11, 2024 Sivan Schipper, Kabir Nigam, Yasmin Schmid et al. 34 citations

Psychedelic-assisted therapy using psilocybin or LSD may help treat anxiety, depression, and existential distress in people with life-threatening diseases, and appears well tolerated with no serious adverse events reported in reviewed studies. However, the evidence is low to very low certainty, meaning results are uncertain and could change with future research. As of 2024, these drugs remain illegal in many countries. Blinding issues and small sample sizes limit confidence; more rigorous studies with active placebos and larger samples are needed. Research is restricted in the US due to Schedule I classification but is increasing.

Acceptability of psilocybin‐assisted group therapy in patients with cancer and major depressive disorder: Qualitative analysis

Cancer December 18, 2023 Yvan Beaussant, Kabir Nigam, Zachary Sager et al. 22 citations

Patients with cancer and depression who received psilocybin-assisted therapy in a group setting found the approach generally acceptable. The group sessions increased their sense of safety and preparedness, fostered connection and belonging, and deepened the meaning of their experience, opening dimensions of self-transcendence and compassion. Key factors influencing acceptability included the therapeutic framework, the complementary role of individual sessions, and group size and structure. The findings suggest that combining group and individual sessions may enhance perceived safety and efficacy compared to either format alone, offering a scalable model for integrating psilocybin-assisted therapy into cancer care.

Set and setting in psilocybin-assisted therapy: A qualitative study of patients with cancer and depression.

General hospital psychiatry January 1, 2025 Yvan Beaussant, Elise Tarbi, Kabir Nigam et al. 3 citations

Psilocybin-assisted therapy (PAT) is promising for cancer-related depression, but little is known about how the therapeutic context affects patient experiences. In interviews with 28 patients with cancer and depression who participated in a clinical trial, participants described the psilocybin experience as intense and demanding. Therapeutic benefits were closely tied to their ability to "surrender"—accepting and remaining open to the experience's intensity and unpredictability. A safe, supportive, and ethical environment was critical for trust and engagement. Preparation and integration were key to maximizing benefit. Music played a variable role, sometimes enhancing and other times distracting. The clinical setting provided safety, while ceremonial elements added meaning.

Psilocybin-assisted therapy for demoralisation in hospice patients: feasibility, safety and preliminary efficacy

BMJ Supportive & Palliative Care November 3, 2025 Yvan Beaussant, Zachary Sager, Caitlin W. Brennan et al. 1 citation

A single 25 mg dose of psilocybin, combined with preparation and integration sessions, was safely administered to ten terminally ill home hospice patients. No serious adverse events occurred. Demoralization scores dropped by an average of 8.8 points three weeks after the session, despite patients' ongoing physical decline. Grief and peace themes were common during the drug sessions. Although most participants rated the treatment favorably, some found the emotional intensity challenging. The results suggest that psilocybin-assisted therapy can be feasibly and safely integrated into hospice care, but larger studies are needed to confirm its benefits.

“To Have the Encounter with Our Own Finiteness in that Existential Way”: Descriptions of Existential Experience in Patients with Cancer and Major Depression Participating in Psilocybin-Assisted Group Therapy

Psychedelic Medicine October 8, 2025 Elise C. Tarbi, Skye A. Miner, Kabir Nigam et al. 1 citation

Patients with cancer and depression describe their cancer experience as deepening their awareness of mortality and prompting them to reprioritize relationships and efforts. In a trial of psilocybin-assisted group therapy, participants sought not only relief from depression but also a new perspective on existential worries and spiritual resources. After treatment, they reported lasting effects including an enhanced sense of meaning, agency, aliveness, and connectedness, describing the experience as a healing, unfolding transformation. The findings illuminate how psilocybin-assisted therapy may address existential suffering and foster personal growth in this population.

The Experience of Women With Breast or Gynecological Cancer After Participation in an Online Mindfulness-Based Cancer Recovery (e-MBCR) Program: Secondary Outcomes Analysis of a Pilot Mixed Methods Randomized Controlled Trial.

Psycho-oncology November 1, 2025 Marie-Estelle Gaignard, Dominica Martin, Jelena Stanic et al.

An online mindfulness program for women with breast or gynecological cancer reduced depression with a medium effect size compared to a control group, though other psychological measures like anxiety, spiritual well-being, and post-traumatic growth showed only favorable trends without statistical significance. At three months, most effects diminished. Qualitative interviews revealed four themes: a safe environment, skill acquisition, enhanced well-being, and exposure to cancer memories. The latter prompted beneficial inner work for most but was deeply challenging for four participants. The program fostered self-exploration and self-efficacy, but challenging experiences also emerged.

[Psychedelic-assisted psychotherapy in palliative medicine].

Revue medicale suisse December 20, 2023 Amandine Schaller, Géraldine Bourquin, Indira Amorim Araujo et al.

Psychedelic-assisted psychotherapy (PAP) combines preparation, substance intake, and integration of experiences to facilitate profound psychospiritual change. Despite methodological and administrative hurdles, interest in this innovative approach continues to grow because of its potential to offer remission where conventional approaches have shown little benefits.
