Controlled Substances Act (CSA)

This law brings together a number of laws regulating the manufacture and distribution of narcotics, stimulants, depressants, hallucinogens, anabolic steroids, and chemicals used in the illicit production of controlled substances. All substances are placed in one of five schedules, based on medicinal value, harmfulness, and potential for abuse or addiction, with Schedule 1 reserved for the most dangerous drugs that have no recognized medical use.
