Which federal agency is responsible for enforcing medication laws in the United States?

The Food and Drug Administration (FDA) is the federal agency tasked with enforcing medication laws in the United States. This agency is responsible for regulating the safety and efficacy of medications, including both prescription and over-the-counter drugs. The FDA ensures that new medications undergo rigorous testing for safety and effectiveness before they can be marketed and sold to the public. Additionally, the FDA monitors ongoing safety data and can take action if medications are found to pose risks after they are approved.

In contrast to the FDA's role, the Centers for Disease Control and Prevention focuses primarily on public health and disease prevention, rather than specifically regulating medications. The National Institutes of Health is mainly concerned with biomedical research and the advancement of medical knowledge, rather than enforcing medication laws. The Environmental Protection Agency, on the other hand, is focused on environmental protection and related regulations, not directly related to the enforcement of medication laws. Thus, the FDA is the definitive agency when it comes to the regulation and enforcement of laws concerning medications in the United States.
