Final answer:
The National Institute for Health is not a federal regulatory agency; it focuses on biomedical and public health research, while the others listed are regulatory agencies.
Step-by-step explanation:
The question asks which entity is not a federal regulatory agency. Among the given options, the Drug Enforcement Agency (DEA), Food and Drug Administration (FDA), and the Centers for Disease Control and Prevention (CDC) are indeed federal regulatory agencies with various capacities for regulation and enforcement of laws related to public health and safety.
However, the National Institute for Health (NIH) is not a regulatory agency; instead, it is the primary agency of the United States government responsible for biomedical and public health research.
The Food and Drug Administration (FDA) is a federal regulatory agency responsible for protecting and promoting public health through the regulation and supervision of various products, including food safety, pharmaceutical drugs, medical devices, and cosmetics.
Therefore, the Food and Drug Administration (FDA) is NOT a federal regulatory agency.
