To accomplish this mission, DEA has special agents, diversion investigators, intelligence analysts, and support personnel stationed in 65 offices in 45 countries throughout the world. In the area of intelligence, DEA collects, analyzes, and disseminates strategic intelligence on cultivation, production, and trafficking trends and operational intelligence on international drug trafficking organizations. DEA provides formal training in drug enforcement techniques to foreign officials at U.S. schools and also maintains teams of agents who travel throughout the world to conduct training sessions for foreign police officers on intelligence collection, technical equipment, and investigative procedures. Some progress has been made by DEA and host governments in the interdiction, eradication, and seizure of drugs in such countries as Peru, Colombia, Bolivia, Ecuador, Brazil, Panama, Mexico, Honduras, Paraguay, and the Caribbean Islands. While DEA tends to focus on Latin America as the source of illicit drugs entering the United States, drug production and trafficking are also significant in Southeast Asia, Southwest Asia, and Europe. DEA is committed on the international front to reducing the supply of cocaine from Latin America; the supply of heroin from the Middle East, Asia, and Mexico; and the supply of marijuana from worldwide sources.
