Which law established the schedule classification for controlled substances?

The Comprehensive Drug Abuse Prevention and Control Act is the legislation that established the scheduling classification for controlled substances. This law, enacted in 1970, created a framework for regulating the manufacture, distribution, and dispensing of drugs that have the potential for abuse and dependency. Under this Act, substances are categorized into different schedules (Schedule I through Schedule V) based on their potential for abuse, accepted medical use, and safety or dependence liability. This scheduling system is essential for maintaining strict controls over powerful drugs, thereby helping to prevent abuse and promote public safety.

In contrast, the other laws mentioned address different aspects of drug regulation. The Drug Price Competition and Patent Term Restoration Act primarily deals with the expiration of patents for brand-name drugs and the approval process for generic drugs. The Food, Drug, and Cosmetic Act governs the safety and efficacy of foods, drugs, and cosmetics but does not specifically address controlled substances. The Poison Prevention Packaging Act focuses on the protection of children from hazardous substances, particularly in ensuring that medications are packaged in a way that prevents accidental ingestion. Hence, these laws do not pertain to the scheduling of controlled substances as established by the Comprehensive Drug Abuse Prevention and Control Act.
