The Endocannabinoid System (ECS) is a recently discovered group of endogenous cannabinoid receptors found throughout the body. The endocannabinoid receptors that make up the ECS are located in our Central Nervous System (CNS), Peripheral Nervous System (PNS), and Immune System. Our CNS includes our brain and spinal cord, while the PNS acts as a communication network linking our CNS to the rest of our body.
Our brains contain the heaviest concentration of cannabinoid receptors, but there’s no shortage of them in our organs, tissues, glands, and more. The saturation of ECS receptors throughout our body is part of why CBD has so many uses and is so effective.
