In recent years Latin America has become the principal source of narcotic drugs on the illicit United States market. Five of the nine countries granted top-priority status in State Department narcopolitics are located in Latin America. Mexico, having earlier supplied 80% of the heroin used by American addicts, is currently the source of approximately 40% of the drug. Coca grown primarily in Bolivia and Peru, shipped through Ecuador, and processed into cocaine in Colombia monopolizes the world market. In the wake of Mexico's highly successful herbicide campaign, Colombian marijuana has come to dominate the American pot scene. And again in response to U.S. demand, Colombia has become the world's foremost manufacturer of illicit methaqualone.
