The Code of Federal Regulations (CFR) is a comprehensive codification of the general and permanent rules published by U.S. federal agencies, organized into 50 titles covering various regulatory areas. Title 21 specifically governs food and drugs, detailing guidelines from the Food and Drug Administration, the Drug Enforcement Administration, and the Office of National Drug Control Policy. The CFR and its online counterpart enhance public access to regulatory information and streamline finding necessary regulations, particularly in the pharmaceutical industry.
