Cannabidiol (CBD) is a phytocannabinoid, one of 113 identified cannabinoids in cannabis plants, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract.[18] Medically, it is an anticonvulsant used to treat multiple forms of epilepsy.[4] It was discovered in 1940 and, as of 2024 clinical research on CBD included studies related to the treatment of anxiety, addiction, psychosis, movement disorders, and pain, but there is insufficient high-quality evidence that CBD is effective for these conditions.[19][20][21][22] CBD is sold as an herbal dietary supplement and promoted with yet unproven claims of particular therapeutic effects.[23]

Cannabidiol can be taken internally in multiple ways, including by inhaling cannabis smoke or vapor, swallowing it by mouth, and through use of an aerosol spray into the cheek.[5][6] It may be supplied as CBD oil containing only CBD as the active ingredient (excluding THC or terpenes), CBD-dominant hemp extract oil, capsules, dried cannabis, or prescription liquid solution.[4][21] CBD does not have the same psychoactivity as THC,[24][25] and can modulate the psychoactive effects of THC on the body if both are present.[18][24][26][27] Conversion of CBD to THC can occur when CBD is heated to temperatures between 250–300 °C, potentially leading to its partial transformation into THC.[28]

In the United States, the cannabidiol drug Epidiolex was approved by the Food and Drug Administration (FDA) in 2018 for the treatment of two seizure disorders.[4] While the 2018 United States Farm Bill removed hemp and hemp extracts (including CBD) from the Controlled Substances Act, the marketing and sale of CBD formulations for medical use or as an ingredient in dietary supplements or manufactured foods remains illegal under FDA regulation, as of 2024.[29][30]
