The State Department's Bureau of International Narcotics Matters, the Drug Enforcement Administration, and the Agency for International Development share responsibilities under the international narcotics control program. During fiscal year 1987, these agencies provided $35.9 million to Burma, Thailand, and Pakistan to assist host governments in crop control, interdiction, law enforcement, and training and development assistance. The study involved interviews with key officials and an examination of relevant records in accordance with generally accepted government auditing standards. United States-supported crop control, enforcement, and interdiction efforts in the three countries have not produced major reductions in opium production, and it is not likely that such reductions will be achieved in the near future. Law enforcement organizations in these countries have basic problems which inhibit effective enforcement and interdiction, including narcotics-related corruption and weak narcotics laws. Crop control programs have not been effectively managed, and development efforts did not fully support narcotics reduction goals. The study offers process recommendations to improve monitoring and goal-setting. 6 tables.
