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."
Bureau of Drug Abuse Control
The Bureau of Drug Abuse Control was formed as a part of the United States Food and Drug Administration in February 1966 and existed until 1968 when it was merged with the Federal Bureau of Narcotics to form the Bureau of Narcotics and Dangerous Drugs. It was later combined with various other agencies to establish the Drug Enforcement Administration on July 1973.
