Roughly 25 years ago researchers discovered a new regulatory system that runs throughout the body. They found it after studying the way the body interacts with the chemical compounds produced by cannabis plants. This system has receptors throughout the body and works to maintain homeostasis (balance) within the body.

Scientists have found two primary receptors within the endocannabinoid system, the CB1 receptor and the CB2 receptor. CB1 receptors are the most prominent. They are largely found in areas of the brain and central nervous system such as the hippocampus, cerebellum and basal ganglia, to name a few. It also extends outwards, though, and CB1 receptors have been found in the liver, reproductive system, cardiovascular system, the skeletal system and in various muscles. CB2 receptors are less prevalent and are mostly found in peripheral body systems.
