The regulation and control of the use of narcotic drugs has long been recognized as the joint responsibility of the state and federal governments, and co-operation between the two is specifically directed in the Federal Act. The purpose of the Uniform Narcotic Drug Acts of the states is to parallel and supplement the Federal Narcotic Laws. Federal officials, in theory, concentrate on interstate traffickers, and state officials on intrastate violations. In reality, however state and federal agents both co-operate in policing the illicit traffic. The Federal Bureau of Narcotics consists of a force of about 260 men, with which it must guard a border of approximately 9,000 miles. It is evident, therefore, that the states and municipalities should assume the burden of enforcement, and thus permit the federal force to concentrate on the broader aspects of the national and international problem.
