Heroin Movement Worldwide
Unlike coca, which is concentrated in South America, opium production occurs in three source regions — Southeast Asia, Southwest Asia, and Latin America — creating a worldwide problem. While an undetermined amount of the opium is consumed in the producing regions, a significant amount of the drug appears to be converted to heroin and sent to the primary consuming markets — Europe and North America. The routes, volume, and methods for the transshipment of heroin vary between the producing regions. Heroin from all three regions reaches the United States, using all forms of air, maritime, and overland conveyances. Rising purity levels and lower prices have fueled heroin’s popularity.
