A Note on CBD: It's All in a Name

I recently saw an article with the following title: “Medical cannabis relieves symptoms in children with autism.” On reading it, I realized that the Drug Target Review was talking about cannabidiol, otherwise known as CBD, not THC (tetrahydrocannabinol, the psychoactive ingredient in cannabis). I also realized the words cannabis and marijuana are no longer useful in talking about marijuana now that CBD has been moved to Schedule V of the Controlled Substances Act when manufactured by GW Pharmaceuticals. Still, it is common to see CBD lumped with the hundreds of other cannabinoids, especially if not produced by a Food and Drug Administration (FDA)–approved pharmaceutical company where it is still classified as Schedule I by the Drug Enforcement Administration (DEA). I think this has implications for popular understanding and clinical utility.
