The endocannabinoid system is a molecular system responsible for regulating and balancing many processes in the body, including immune response, communication between cells, appetite and metabolism, memory, and more. It is through this system of receptors and metabolic enzymes that cannabinoids interact with the human body and trigger beneficial effects and promote homeostasis. Despite the integral role the endocannabinoid system has in human body function, it was discovered relatively recently and much of its importance is only just becoming understood by scientists and the medical community at large.
