For the first time in 46 years, the Drug Enforcement Administration has changed its stance on the marijuana compound CBD. According to Business Insider, rather than reclassifying CBD entirely, the agency changed how it regulates federally-approved drugs made with the compound. Those drugs are now classified as Schedule 5 drugs, meaning they're the least-strictly regulated. At the moment, only one such drug exists--an epilepsy drug called Epidolex. Researchers, advocates, and entrepreneurs say the move is good news for the CBD industry as a whole.
