The Code of Federal Regulations (CFR) is the codification of rules and regulations issued by federal agencies in the United States. It is divided into 50 titles that represent broad subject areas subject to regulation, such as transportation, banks and banking, food and drugs. Within each title are chapters and parts that contain the specific regulations. The CFR is updated annually and published online daily. Title 21 of the CFR governs regulations relating to food and drugs and is divided into three chapters covering the Food and Drug Administration, Drug Enforcement Administration, and Office of National Drug Control Policy.
