Problem: Drug trafficking is the major illegal source of income in Tajikistan as it is an important transit country for Afghan narcotics bound for Russian and, to a lesser extent, Western European markets; some opium poppy is also raised locally for the domestic market. However, with the increasing assistance from international organizations, such as UNODC, and cooperation with the US, Russian, EU and Afghan authorities a level of progress on the fight against illegal drug-trafficking is being achieved. Tajikistan holds third place in the world for heroin and raw opium confiscations (1216.3 kg of heroin and 267.8 kg of raw opium in the first half of 2006). Drug money corrupts the country's government; according to some experts the well-known personalities that fought on both sides of the civil war and have held the positions in the government after the armistice was signed are now involved in the drug trade. UNODC is working with Tajikistan to strengthen border crossings, provide training, and set up joint interdiction teams. It also helped to establish Tajikistani Drug Control Agency.
