It proposed the creation of a single federal agency to enforce the federal drug laws as well as consolidate and coordinate the government's drug control activities . Congress accepted the proposal, as they were concerned with the growing availability of drugs . As a result, the Bureau of Narcotics and Dangerous Drugs (BNDD), the Office of Drug Abuse Law Enforcement (ODALE); approximately 600 Special Agents of the Bureau of Customs, Customs Agency Service, and other federal offices merged to create the DEA . </P>
