As more and more states legalize the use of marijuana, a product known as CBD oil has surged in popularity. A chemical compound found in the cannabis plant, CBD, or cannabidiol, is non-intoxicating and does not cause the noticeable euphoric effects associated with tetrahydrocannabinol (or THC, another marijuana compound). Products marketed as CBD oil may contain THC.
Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining the subject of an FDA investigational new drug evaluation, and is not considered legal as a dietary supplement or food ingredient as of December 2018. Federal illegality has made it difficult historically to conduct research on CBD. CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.
There is no scientific evidence or research on CBD as an effective treatment for migraine—in large part because it has not been formally studied. However, it may still be a viable topical option for some patients with joint and muscle pain associated with migraine. “If you have a lot of neck pain or soreness, it is perfectly reasonable to use CBD oil. It may even prevent nausea and vomiting,” Dr. Silberstein says.
In fact, the U.S. Food and Drug Administration (FDA) approved Epidiolex (a drug made with a purified form of CBD oil) in June 2018 for the treatment of seizures associated with two rare and severe forms of epilepsy in patients 2 years of age and older. These two epilepsy forms are known as Lennox-Gastaut syndrome and Dravet syndrome. Epidiolex is the first FDA-approved drug that contains a purified drug substance derived from marijuana.
