Heroin is manufactured from opium poppies cultivated in four primary source areas: South America, Southeast and Southwest Asia, and Mexico. Although Afghanistan produces the majority of the world’s heroin, South American heroin has become the most prevalent type available in the U.S., particularly in the Northeast, South and Midwest. The particular form known as “black tar” from Mexico, a less pure form of heroin, is more commonly found in the western and southwestern United States. This heroin may be sticky like roofing tar or hard like coal, with its color varying from dark brown to black.
