Mexico's Drug Cartels

"Mexico, a major drug producing and transit country, is the main foreign supplier of marijuana and a major supplier of methamphetamine to the United States. Although Mexico accounts for only a small share of worldwide heroin production, it supplies a large share of heroin consumed in the United States. An estimated 90% of cocaine entering the United States transits Mexico. Violence in the border region has affected U.S. citizens. More than 60 Americans have been kidnaped in Nuevo Laredo, and in July 2007, Mexican drug cartels reportedly threatened to kill a U.S. journalist covering drug violence in the border region. The United States and Mexico are reportedly negotiating a new counternarcotics initiative. Source: Congressional Research Service, Library of Congress
