Human physiological system
The endocannabinoid system (ECS) is a complicated cell-signaling mechanism discovered by researchers studying THC, a well-known cannabinoid, in the early 1990s. Cannabis is rich in chemicals known as cannabinoids.
Experts are still attempting to figure out ECS. However, we know that it regulates various functions and processes such as sleep, mood, appetite, memory, and reproduction.
For ECS to operate, it involves endocannabinoids, receptors, and enzymes.
