Black-tar heroin, a potent, inexpensive, semi-processed form of the drug that has spread across the United States, driven by the entrepreneurial energy and marketing savvy of immigrants from a tiny farming county in Mexico.Immigrants from Xalisco, in the Pacific coast state of Nayarit, Mexico, have brought the heroin north over the last decade, and with it a highly effective business model featuring deep discounts and convenient delivery by car. Their success is a major reason why Mexican black tar has seized a growing share of the U.S. heroin market, according to government estimates.
Xalisco networks are decentralized, with no all-powerful boss, and they largely avoid guns and violence. Staying clear of the nation's largest cities, where established organizations control the heroin trade, Xalisco dealers have cultivated markets in the mountain states and parts of the Midwest and Appalachia, often creating demand for heroin in cities and towns where there had been little or none. In many of those places, authorities report a sharp rise in heroin overdoses and deaths.Before the string of fatal overdoses in 2007, "we didn't even consider heroin an issue," said Huntington Police Chief Skip Holbrook.
Xalisco dealers have been particularly successful in areas where addiction to prescription painkillers like OxyContin was widespread. Many of those addicts, mainly young middle- and working-class whites, switched to black tar, which is cheaper and more powerful.In York County, S.C., pain-pill addicts became hooked on black tar purchased in Charlotte, N.C., half an hour away. "We used to get maybe one overdose death a year" caused by opiates, said Marvin Brown, commander of the county's drug unit. "We had six in the first six months" of 2009.In the suburbs south of Salt Lake City, heroin was unheard of until dealers from Xalisco arrived, said Lt. Phil Murphy of the Utah County Major Crimes Task Force. Now, he said, young people looking for an alternative to pain pills drive to Salt Lake to score black-tar heroin.
University towns have been especially fertile markets for Xalisco heroin. Authorities in Boulder and Fort Collins, Colo. -- home to the University of Colorado and Colorado State University, respectively -- report increased overdoses caused by black-tar heroin purchased from dealers in Denver.Ohio has also become a center of Xalisco networks, and it was through a junkie in Columbus that black tar made its way to Huntington.
