The United Nations Office of Drugs and Crime, or UNODC, has described Iran as having one of the largest opiate-using populations in the world, in part because of its proximity to the narcotics' source. 

In 2008,  heroin seizures around the world reached a record of 73.7 metric tons. Iran and Turkey accounted for more than half of the total. And Iran continues to be the world leader in the amount of heroin it seizes, said Tehran-based UNODC representative Antonino de Leo.
