CBD affect the human body by attaching themselves to various receptors. Other cannabinoids are produced by the body and there are CB1 and CB2 receptors. The CB1 receptors are located all throughout the body and many of these can be found in the brain. These receptors are responsible for the pain, mood, coordination, movement, appetite, emotions, thinking, movement, memories, and other functions. The THC affects these receptors. On the other hand, CB2 receptors are mainly in our immune system and affect inflammation and pain. Even though the CBD does not directly attach here, it directs the body to utilize cannabinoids more.
