Agencies of Enforcement
At the inception of the drug laws, no special agencies to deal with violators were set up. The original legislation was, theoretically, a tax act; therefore the federal agency responsible was the Bureau of Internal Revenue nested in the Department of the Treasury. In 1927, a new bureau, the Bureau of Prohibition, was established. It also was part of the Department of the Treasury, and took on the responsibilities that formerly belonged to the Bureau of Internal Revenue. This change was really just an internal reorganization.
