Cannabidiol (CBD) is a chemical compound found in the cannabis plant, specifically in hemp and marijuana. It is one of over 100 cannabinoids identified in cannabis and can make up to 40% of the plant's extract

. Unlike tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, CBD does not cause a "high" or intoxication

. CBD is non-impairing and non-addictive, and it interacts with the body's endocannabinoid system, which regulates various functions such as pain sensation and mood

. It is available in many forms, including oils, capsules, lotions, foods, and cosmetics

. Medically, CBD is approved by the U.S. Food and Drug Administration (FDA) in the prescription drug Epidiolex for treating certain seizure disorders like Dravet syndrome and Lennox-Gastaut syndrome

. Beyond epilepsy, CBD is being studied for potential benefits in anxiety, pain, inflammation, depression, and other conditions, though high-quality evidence for these uses is still limited

. CBD products derived from hemp (cannabis plants with less than 0.3% THC) were federally legalized in the U.S. by the 2018 Agriculture Improvement Act, but regulations vary by state and the FDA restricts CBD use in foods and dietary supplements

. In summary, CBD is a non-psychoactive cannabis compound with potential therapeutic properties, widely used in various consumer products, and legally distinct from THC-containing marijuana
