#### Clinical Takeaway

Cannabinoids have been shown to directly interact with voltage-gated sodium channels involved in pain signaling, reducing their activity in ways that may help dampen nerve-based pain. This effect appears to occur independently of the traditional [cannabinoid receptors](https://cedclinic.com/citral-cannabinoid-receptor-2-activation-pain-relief/) (CB1 and CB2), suggesting an additional biological pathway through which [cannabis compounds](https://cedclinic.com/cannabis-terpene-synergy-entourage-effect/) influence pain. The findings offer a plausible mechanistic explanation for the analgesic effects observed in clinical practice, particularly for [neuropathic pain](https://cedclinic.com/cannabis-for-pain-relief/) conditions.
