Many individuals suffer from nerve pain: diabetic neuropathy, migraines (yes, they are considered a nerve pain), trigeminal neuralgia, chemotherapy-induced, and idiopathic (unknown cause).
THC and CBD work on the endocannabinoid system in our bodies. There are 2 types of cannabinoid receptors - CB1 and CB2.
CB1 receptors are mainly found in the nervous system and brain. The easy way to remember is you have "1" brain (CB "one"). CB2 receptors are mainly found throughout the body - on our organs and tissues ( We have 2 lungs, 2 kidneys, etc...CB "two").
When we experience pain in the nervous system, both THC and CBD can helped to reduce pain by binding to these CB1/2 receptors. CBD is non-psychoactive and the more CBD in a medical cannabis product, the less psychoactive effects one will experience.
Of course it will be helpful once we have more research to further investigate what particular doses will work for various types of nerve pain and interactions with current pharmaceuticals already being used for treatment of said pain.
