The endocannabinoid system contains a set of endocannabinoids that are produced from within the body. These compounds activate a network of cannabinoid receptors throughout the body. Two primary receptors have been identified, CB1 and CB2. This system is involved in regulating a wide variety of physiological and cognitive processes. The ECS plays a role in appetite, pain sensation, mood, memory, metabolism, immune function, sleep and more.

Endocannabinoids and their receptors are found throughout the brain, immune cells, organs, connective tissues, and glands. The system performs a unique role in each location that it resides, yet the overall goal is the same. The endocannabinoid system works to achieve balance through homeostasis. In practical terms, the ECS works to create an inner balance despite external influences and environmental disturbances.

The identification of receptors and the endogenous cannabinoid compounds produced in the body has scientifically advanced human understanding of biology, health, and disease.
