#### Clinical Takeaway

Cannabinoids modulate pain signaling by affecting sodium channels involved in nerve impulse transmission, which represents a specific mechanism for pain relief. This action occurs at ion channels that are critical for transmitting pain signals throughout the nervous system. The evidence suggests cannabinoid-sodium channel interactions may explain why some patients experience reduced pain with [cannabis-based treatments](https://cedclinic.com/cannabis-medical-clinic-experience-beyond-smoking-vaping/).
