Pure Food and Drug Act
The 1906 Act paved the way for the eventual creation of the Food and Drug Administration (FDA) and is generally considered to be that agency's founding date, though the agency existed before the law was passed and was not named FDA until later. "While the Food and Drug act remains a foundational law of the FDA mission, it's not the law that created the FDA. [Initially,] the Bureau of Chemistry (the precursor to the FDA) regulated food safety. In 1927, the Bureau was reorganized into the Food, Drug, and Insecticide Administration and the Bureau of Chemistry and Soils. The FDIA was renamed the FDA in 1930."
Federal Bureau of Narcotics
Anslinger retired in 1962 and was succeeded by Henry Giordano, who was the commissioner of the FBN until it was merged in 1968 with the Bureau of Drug Abuse Control, an agency of the Food and Drug Administration, to form the Bureau of Narcotics and Dangerous Drugs, an agency of the United States Department of Justice. The BNDD was a predecessor agency of the current Drug Enforcement Administration (DEA).
