You have an endocannabinoid system (ECS)! It’s comprised of receptors throughout the body made to interact with chemicals found in cannabis. The ECS is found in humans and many animals. The endocannabinoid system is a group of specialized lipids, their receptors, and the enzymes that produce and degrade them.
Through direct and indirect actions, endocannabinoids are known to modulate and influence a variety of physiological systems, including appetite, pain, inflammation, thermoregulation, intra-ocular pressure, sensation, muscle control, energy balance, metabolism, sleep, stress response, motivation/reward, mood, and memory.
