Which law classified drugs by abuse potential and created strict controls over distribution, storage, and use?

• A. Harrison Act of 1914
• B. Marijuana Tax Act of 1937
• C. Boggs Act of 1951
• D. Controlled Substances Act of 1970

Answer: (D)

This question tests how federal drug regulation evolved into a system that ranks drugs by abuse potential and imposes strict controls on their distribution, storage, and use. The law that does this is the Controlled Substances Act of 1970. It created a formal scheduling framework (Schedules I through V) that evaluates each substance based on its potential for abuse, medical use, and safety. This scheduling drives the regulatory requirements for manufacturing, distributing, prescribing, and record-keeping, and it gives authorities strong enforcement powers to control handling of these substances. Earlier statutes mainly taxed or penalized drug offenses and did not establish a comprehensive nationwide scheduling system or the same level of regulatory control. For example, earlier acts treated narcotics through taxes or registration and penalties rather than creating a unified classification with strict controls. Therefore, the Act that best fits this description is the one that codified the scheduling system and rigorous controls: the Controlled Substances Act.
