Which act is abbreviated CSA?

• A. Federal Food, Drug, and Cosmetic Act
• B. Controlled Substances Act
• C. Kefauver Harris Amendment
• D. Harrison Narcotic Act

Answer: (B)

Understanding what CSA stands for and what it governs is the key. CSA stands for Controlled Substances Act, enacted in 1970 to regulate manufacturing, distribution, and dispensing of controlled substances. It established a scheduling system (Schedules I–V) to categorize drugs by potential for abuse and accepted medical use, guiding how they are prescribed and enforced. It also led to the creation of the DEA to enforce these controls. This is why this option is the best match for the abbreviation CSA.

The other items refer to different laws or amendments with other common abbreviations: the Federal Food, Drug, and Cosmetic Act is usually shortened to FD&C Act; the Kefauver Harris Amendment is an amendment to that act (not CSA); the Harrison Narcotic Act predates the CSA and focused on taxing and regulating opiates and coca leaves, not the controlled substances framework.
