In 1983, the FBI joined other organizations in the Organized Crime Drug Enforcement Task Force Program. This program has been effective in battling traditional drug traffickers and the new generation of violent drug criminals. Since 1986, the FBI's role in domestic drug enforcement has been focused by a National Drug Strategy that is specifically built around the agency's ability to conduct long-term, sustained investigations of criminal enterprises. The strategy rests on five aims: investigate major drug trafficking enterprises to dismantle them and seize their assets; expand and enhance the drug intelligence data base; identify and project drug trafficking activities on a national scale; concentrate resources on major drug trafficking centers; and assist law enforcement agencies that operate outside primary drug centers with investigations of major drug trafficking enterprises. In 1989, FBI investigations resulted in over 2,900 felony drug convictions and the seizure of over $170 million of drug traffickers' illegal profits. The FBI has also created a Drug Demand Reduction Program, with special agents trained in demand reduction who work in local communities. In 1990, the FBI will add the subject of drug demand reduction to the FBI National Academy's curriculum. The FBI tests special agents for drug use before they are accepted into the FBI and also tests employees who are under reasonable suspicion of drug use. Drug testing, however, is only one of four major elements in the FBI's employee drug deterrence program, the other three elements are employee education, supervisory training, and employee assistance.
