Overview Information
Cannabidiol is a chemical in the
Cannabis sativa plant, also known as marijuana. Over 80 chemicals, known as cannabinoids, have been identified in the Cannabis sativa plant. While delta-9-tetrahydrocannabinol (THC) is the major active ingredient,
cannabidiol makes up about 40% of cannabis extracts and has been studied for many different uses. According to the U.S. Food and Drug Administration (FDA), because cannabidiol has been studied as a new drug, products containing cannabidiol are not defined as dietary supplements. But there are still products labeled as dietary supplements on the market that contain cannabidiol.
People take cannabidiol by mouth for anxiety, bipolar disorder, a muscle disorder called dystonia, epilepsy, multiple sclerosis, Parkinson’s disease, and schizophrenia.
People inhale cannabidiol to help quit smoking.
A prescription-only nasal spray (Sativex, GW Pharmaceuticals) containing both THC and cannabidiol is used for pain and muscle-tightness in people with multiple sclerosis in over 25 countries outside of the United States.
How does it work?
Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.
