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.

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 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.

Classic psychedelics were the only substances reported to reduce obsessive compulsive disorder (OCD) symptoms in a retrospective online survey of 174 people who used psychoactive drugs. Symptom reduction was linked to the intensity of acute effects, which correlated with dose. Therapeutic effects lasted from weeks to months, but no factor predicted their persistence. Frequency of subsequent use was predicted by the magnitude and persistence of the effect, though overall use was limited. The findings support the possibility that classic psychedelics can reduce OCD symptoms, but careful evaluation of effect persistence is still needed.

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.

This Cochrane protocol outlines a planned review to evaluate whether psychedelic- or entactogen-assisted therapy is beneficial and safe for adults in palliative care who suffer from anxiety, depression, or existential distress. The review will compare such therapy against placebo or active treatments like antidepressants. The protocol describes the methods for searching and analyzing studies, but no results are reported yet.

Anxiety, depression, adjustment disorder, and existential distress in seriously ill people often resist existing medical or behavioral interventions. A growing body of evidence suggests the safety and efficacy of psychedelic-assisted therapies (PATs) to improve these outcomes. As societal norms around the stigma of psychedelic agents shift, interest in integrating these treatment modalities into serious illness care increases. This article describes aspects of serious illness care that might be amenable to PATs, reviews evidence documenting the safety and efficacy of PATs in serious illness care, and highlights opportunities and challenges moving forward.

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.

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.

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.

Experts in palliative care, oncology, psychiatry, and psychedelic-assisted therapy identified special considerations for using psychedelics near the end of life. They emphasized a non-medicalized setting, the potential to reduce preparation time, and the importance of addressing anxiety, depression, and spiritual distress. Dosing flexibility was recommended: low-to-medium doses for relational issues, higher doses for transcendental experiences. Therapists need knowledge of mystical states, existential aspects of life-threatening illness, and their own inner work. The findings provide a first step toward specific treatment recommendations for psychedelic-assisted therapy in palliative care.

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 (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.
