L. 91--513, 84 Stat. 1236, enacted October 27, 1970, is a United States federal law that, with subsequent modifications, requires the pharmaceutical industry to maintain physical security and strict record keeping for certain types of drugs . Controlled substances are divided into five schedules (or classes) on the basis of their potential for abuse, accepted medical use, and accepted safety under medical supervision . Substances in Schedule I have a high potential for abuse, no accredited medical use, and a lack of accepted safety . From Schedules II to V, substances decrease in potential for abuse . The schedule a substance is placed in determines how it must be controlled . Prescriptions for drugs in all schedules must bear the physician's federal Drug Enforcement Administration (DEA) license number, but some drugs in Schedule V do not require a prescription . State schedules may vary from federal schedules . </P> <P> The Controlled Substances Act (CSA), Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970, is the legal foundation of the government's fight against the abuse of drugs and other substances . This law is a consolidation of numerous laws regulating the manufacture and distribution of narcotics, stimulants, depressants, hallucinogens, anabolic steroids, and chemicals used in the illicit production of controlled substances . The act also provides a mechanism for substances to be controlled, added to a schedule, decontrolled, removed from control, rescheduled, or transferred from one schedule to another . </P>
