Clinical Takeaway
Cannabinoids modulate pain signaling by affecting sodium channels involved in nerve transmission, based on laboratory evidence from multiple studies. This mechanism may explain part of cannabinoids’ pain-relieving effects, though human clinical outcomes require further study. Current evidence supports sodium channel modulation as one pathway through which cannabinoids influence pain perception.
