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.

In a double-blind, low-dose controlled trial, 61 patients with moderate-to-severe major depressive disorder received supportive psychotherapy and either two high doses (100 μg then 200 μg) or two low doses (25 μg each) of LSD. At the primary endpoint two weeks after the second session, the high-dose group showed a greater average reduction in self-rated depression scores (11.8 points) compared to the low-dose group (3.9 points), a difference that approached but did not reach statistical significance. Clinician-rated scores also favored the high dose, but significance was lost after adjusting for baseline depression severity. Improvements were numerically maintained through 12 weeks. Adverse events were similar between groups. The authors suggest these exploratory results warrant a larger phase 3 trial.

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.

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.
