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.
