The Endocannabinoid System
Before delving into the effects of cannabis on the brain, it is essential to introduce the endocannabinoid system (ECS). The ECS is a complex network of receptors, neurotransmitters, and enzymes present in the human body, including the brain. Its primary function is to regulate various physiological processes, including mood, memory, pain sensation, appetite, and immune responses. The ECS plays a pivotal role in how cannabis affects the brain.
