CBD can offer an alternative for people who have chronic pain and rely on medications, such as opioids, that can be habit-forming and cause more side effects. However, more research is needed to verify the pain-relieving benefits of CBD oil and other products. Epidiolex, a drug prescribed for epilepsy, is the only CBD product on the market that the Food and Drug Administration (FDA) has approved. There aren’t any FDA-approved, non prescription CBD products. They aren’t regulated for purity and dosage like other medications.
