Which federal agency regulates the use of controlled substances in veterinary medicine?

The Drug Enforcement Administration (DEA) is the federal agency responsible for regulating the use of controlled substances in veterinary medicine. This agency enforces the Controlled Substances Act, which establishes a legal framework for the manufacture, distribution, and use of drugs that are classified as controlled substances due to their potential for abuse and dependence. Veterinarians must register with the DEA to prescribe or administer these substances, ensuring that they are used safely and appropriately in veterinary practice. The regulations set forth by the DEA help to prevent misuse and ensure compliance with federal law.

In contrast, the Food and Drug Administration (FDA) is primarily tasked with overseeing the safety and efficacy of animal drugs but does not have direct regulatory authority over the control of substances. The Centers for Disease Control and Prevention (CDC) focuses on public health and the prevention of disease but is not involved in drug regulation. The U.S. Department of Agriculture (USDA) primarily regulates agricultural practices and animal health programs, rather than the control of substances. Therefore, the DEA is clearly the correct answer regarding the oversight of controlled substances in veterinary medicine.
