Summary
Chronic pain affects 1.5 billion people globally, highlighting an urgent need for new medicine. A review of 21 human studies reveals psychedelics, including psilocybin and lysergic acid diethylamide (a hallucinogen), show promise for chronic pain, especially cancer pain and certain headaches. Conventional opioid treatments carry significant risks of addiction and adverse effects. Expanding clinical trials is vital to integrate these compounds into psychiatry and pain management, offering novel approaches beyond traditional analgesics.
Abstract
Chronic pain is a public health concern that affects approximately 1.5 billion people globally. Conventional therapeutic agents including opioid and non-opioid analgesics have been associated with adverse side effects, issues with addiction, and ineffective analgesia. Novel agents repurposed to treat pain via different mechanisms are needed to fill the therapeutic gap in chronic pain management. Psychedelics such as lysergic acid diethylamide and psilocybin (the active ingredient in psychedelic mushrooms) are thought to alter pain perception through direct serotonin receptor agonism, anti-inflammatory effects, and synaptic remodeling. This scoping review was conducted to identify human studies in which psychedelic agents were used for the treatment of pain. Twenty-one articles that assessed the effects of psychedelics in treating various pain states were included. The present scarcity of clinical trials and small sample sizes limit their application for clinical use. Overall, psychedelics appear to show promise for analgesia in patients with certain headache disorders and cancer pain diagnoses. Future studies must aim to examine the combined effects of psychotherapy and psychedelics on chronic pain.
