<P> 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 . Classification decisions are required to be made on criteria including potential for abuse ( an undefined term ) , currently accepted medical use in treatment in the United States , and international treaties . </P>
