CBD is a non-psychoactive chemical compound — meaning it won’t alter a person’s mental state — that can come from two different cannabis plants: The hemp plant (with less than 0.3 percent THC present) or marijuana plant (where there’s much more psychoactive THC). CBD products tend to be derived from hemp.
There are still plenty of unknowns when it comes to CBD. The FDA has only approved the use of CBD oil in specific cases of epilepsy. Epidiolex, the FDA-approved CBD drug, was placed in the “least restrictive” category of controlled substances by the Drug Enforcement Agency, meaning it’s in the same category with cough medicine Robitussin AC.
