Including CBD, all the cannabinoid compounds act as ligands and attach themselves to specific receptors in our body and produce certain effects. The human body has two types of receptors for cannabinoids – CB1 and CB2 receptors and the body also produces some cannabinoids on its own. The CB1 receptors are located throughout the body, but a large number are located in the brain which regulate various aspects such as coordination, movement, memories, cognition, autonomic, mood, sensory and pain perception, appetite and endocrine functions.
