A systematic review of 20 studies found that psychedelic-assisted therapies show positive effects for symptom control in patients with serious illness, particularly for psychological and spiritual symptoms. Most studies used lysergic acid diethylamide, psilocybin, or N,N-dipropyltryptamine in cancer patients. Adverse effects were physical or psychological, mild to moderate, transient, and self-resolving. The evidence suggests considerable safety of use.

For people with serious illness, psychedelic experiences can transform how they relate to their own finitude. Before the experience, death is a dominant threat, marked by fear and an illness-centered identity. During the psychedelic state, expanded consciousness enables transcendence—symbolic encounters with death, ego expansion, spiritual unity, and emotionally challenging experiences—which allow people to reinterpret suffering as transformative and reconstruct their personal narratives. Afterward, finitude becomes integrated into life with greater acceptance of mortality, reduced death anxiety, and a revaluation of life priorities. The process does not eliminate suffering but involves its traversal and integration, supporting existential adaptation at the end of life.
