Mexican Heroin

Mexican heroin has been a threat to the United States for decades. It is produced, smuggled, and distributed by polydrug trafficking groups, many of which have been in operation for more than 20 years. Nearly all of the heroin produced in Mexico is destined for distribution in the United States. Organized crime groups operating from Mexico produce, smuggle, and distribute the black tar heroin sold in the western United States. Traditionally, trafficking groups operating from Mexico evaded interdiction efforts by smuggling heroin to the U.S. market as they received orders from customers. By keeping quantities small, traffickers hoped to minimize the risk of losing a significant quantity of heroin in a single seizure. Even large polydrug Mexican organizations, which smuggle multiton quantities of cocaine and marijuana, generally limited smuggling of Mexican heroin into the United States to kilogram and smaller amounts. Nevertheless, trafficking organizations were capable of regularly smuggling significant quantities of heroin into the United States.
Although illegal immigrants and migrant workers frequently smuggle heroin across the U.S./Mexico border in 1- to 3- kilogram amounts for the major trafficking groups, seizures indicate that larger loads are being moved across the border, primarily in privately owned vehicles. Once the heroin reaches the United States, traffickers rely upon well-entrenched polydrug smuggling and distribution networks to deliver their product to the market, principally in the metropolitan areas of the midwestern, southwestern, and western United States with sizable Mexican immigrant populations.
Indicative of larger shipments of Mexican heroin being smuggled into the United States are several seizures that occurred in the Southwest in recent years. Following a traffic stop in April 2002 near Pleasanton, Texas - about 25 miles south of San Antonio - Department of Public Safety troopers seized 34 kilograms of brown powder heroin. The heroin bundles, placed inside metal boxes, were found in all four tires of a pickup truck which was headed for San Antonio. In January 2001, the USCS in Del Rio, Texas, seized 42 kilograms of black tar heroin and in December 2000, they seized 27 kilograms of black tar heroin at the Laredo port of entry. Texas has not been the only border state where large amounts of black tar heroin have been seized. In October 2000, 46 kilograms of black tar heroin were seized in Arizona at the San Luis port of entry. This seizure ranks as one of the largest ever made along the Southwest border.
Although recent DEA cases have involved Mexican black tar heroin trafficking groups east of the Mississippi River, there has been no successful, long-term penetration of the East Coast markets by organizations selling Mexico-produced heroin.
