Can Psilocybin Treat Chronic Pain? A New Therapeutic Frontier

Chronic pain remains a massive healthcare burden, impacting nearly 20% of adults worldwide and often proving resistant to conventional therapies. With the opioid crisis underscoring the urgent need for safer alternatives, scientists are revisiting psilocybin—a serotonergic psychedelic compound—as a promising candidate for future pain management.

A recent narrative review synthesising preclinical and clinical evidence suggests psilocybin functions as a multidimensional therapy. In animal models, the compound was shown to promote synaptogenesis—the creation of new connections between neurons—via specific signalling pathways. It also appears to dampen neuroinflammation and modulate 5-HT2A receptors, leading to persistent analgesic (pain-relieving) effects. Notably, these benefits were observed in models of chemotherapy-induced neuropathy and inflammatory pain.

Beyond the physical sensation, chronic pain often involves significant emotional distress. Early clinical studies indicate that psilocybin may address both the sensory and affective components of pain. Patients with advanced cancer and chronic conditions reported improvements in depression, anxiety, and resilience, alongside preliminary signs of physical pain reduction. However, the authors emphasise that current evidence is preliminary. To translate these findings into clinical practice, researchers must conduct robust randomised controlled trials to navigate safety concerns and regulatory barriers.
