Controlled Substances Act The legislation created five Schedules (classifications), with varying qualifications for a substance to be included in each. Two federal agencies, the Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA), determine which substances are added to or removed from the various schedules, although the statute passed by Congress created the initial listing. Congress has sometimes scheduled other substances through legislation such as the Hillory J. Farias and Samantha Reid Date-Rape Prevention Act of 2000, which placed gamma hydroxybutyrate (GHB) in Schedule I and sodium oxybate (the ISOLATED sodium salt in GHB) in Schedule III.[2][3] Classification decisions are required to be made on criteria including potential for abuse (an undefined term),[4][5] currently accepted medical use in treatment in the United States, and international treaties.
