Cannabidiol, also known as CBD, is a non-psychoactive substanceCannabinoids found in the hemp plant ''Cannabis''.
CBD is not psychoactive, and appears to reduce the euphoric effect of THC. It may decrease the rate of THC clearance from the body, perhaps by interfering with the metabolism of THC in the liver. Medically, it appears to relieve convulsion, inflammation, anxiety, and nausea. CBD has a greater affinity for the CB2 receptor than for the CB1 receptor. It is perceived to have more effect on the body.
