Experts are still trying to understand the endocannabinoid system (ECS). It is known to play a role in a range of processes and functions of the body to include sleep, appetite, memory, and mood. The three main areas of the ECS are: endocannabinoids, receptors, and enzymes.

Endocannabinoids are produced, as needed, by the body to assist with internal functions keeping in balance.

Receptors are found throughout the body, and the two known receptors are CB1 and CB2. CB1 is associated with the central nervous system, and CB2 is associated with the immune system. Endocannabinoids bind with receptors to signal the ECS needs to engage.

Enzymes break down the endocannabinoids once they have completed the function. This can be done by either fatty acid hydrolase, and monoacylglycerol acid lipase.

For the body to maintain homeostasis, experts believe the ECS is the primary driver to maintain the internal stability of the body.
