Cannabidiol , or CBD, is a natural substance found in the Cannabis sativa plant. It is one of more than 80 chemical compounds known as cannabinoids in the plant, which is also called marijuana or hemp. The other well-known cannabinoid is tetrahydrocannabinol (THC), which produces the intoxicating effect associated with smoking or consuming marijuana.

CBD has been used to treat some health conditions, including chronic pain and anxiety, and it may help prevent seizures related to rare forms of epilepsy. In 2018, a prescription drug containing CBD, Epidiolex, was approved by the FDA to treat seizures associated with Lennox-Gastaut syndrome and Dravet syndrome. Some research suggests that CBD may reduce inflammation, which could help people with inflammatory conditions such as arthritis and fibromyalgia.

Scientists are still learning about the benefits and risks of CBD. For example, some research shows that CBD may interact with some drugs, such as antidepressants and blood thinners. People should talk with their doctor before using CBD, especially if they take other medicines.

Products marketed for medical use that have not been evaluated by FDA may pose serious risks to patients. The FDA encourages anyone who uses these products to report any side effects to the FDA.
