CBD and the Endocannabinoid System (ECS): The endocannabinoid system (ECS) controls many bodily functions, including mood, pain perception, immune reaction, and more. The ECS is made up of endocannabinoids (which are naturally occurring substances in the body) and cannabinoid receptors (CB1 and CB2). CBD works with these receptors, but the way it works is complicated and not fully known.
