This is the body’s own “cannabis” system. We all have cannabinoid nerve receptors in our brain and elsewhere in the body. We produce chemicals, called endocannabinoids, which lock on to those receptors and perform vital functions. This system is responsible for such things as pain control, mood control, anti-inflammation response, control of bodily movement, epilepsy, etc. The plant cannabinoids, called phytocannbinoids, help that system by also locking on to those receptors. This is why cannabis has so many potential uses.
