Summary
Psychedelic compounds may offer new hope for pain management, showing promising results in treating severe headaches and cancer-related discomfort. Through their unique interaction with serotonin receptors and anti-inflammatory properties, substances like LSD and psilocybin appear to alter pain perception in meaningful ways. Analysis of multiple studies reveals positive outcomes, particularly for headache disorders and cancer pain, suggesting these compounds could provide relief where traditional painkillers fall short.
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.
