America’s heroin epidemic starts in Mexico

America faces its worst drug crisis in decades, with heroin and opioid use tripling since 2010. As various federal agencies roll out their annual strategy reports, the government declared that-as was the case in previous drug frenzies-all of the heroin used in the U.S. comes from abroad. Only now, instead of Southeast Asia’s Golden Triangle or remote South America, the primary source is just next door, in a country with already delicate U.S. relations.

This week, the State Department delivered some 600 pages to Congress detailing the transnational drug trade, putting together data from the U.N., Drug Enforcement Administration, Immigration and Customs Enforcement, and a variety of other entities. “The opioid epidemic demands urgent action as a top priority of U.S. and international drug control efforts,” the report stated.

As much as 94 percent of the heroin entering America comes from Mexico, estimated William R. Brownfield, a man with a complex title (assistant secretary of the Bureau of International Narcotics and Law Enforcement Affairs) who sits at the fulcrum of drug interdiction and diplomatic initiative.

During a conference call Thursday, he explained that, in 2017, a synthetic opioid between 10 and 50 times more potent than heroin, raw fentanyl, is being trafficked through Mexico into the U.S. alongside heroin and cocaine, though it’s largely produced in Asia. (Other commonly known opioids are morphine, oxycodone, and tramadol.)

Between 1988 and 1994, Southeast Asia was the area of origin for the majority of wholesale heroin seizures in the U.S. Then it shifted to South America through 2010. Since then, Mexico has gained market share, according to data from the Heroin Signature Program cited by the DEA.

Between 2010 and 2015, heroin seizures in America increased from 2,763 kilograms to 6,722 kilograms, according to a November report from the DEA, indicating a surge of the drug entering the country. “The U.S. has seen substantial increases in heroin availability in the last seven to 10 years, which has allowed the heroin threat to expand to unprecedented levels,” the report stated. “Increases in heroin production in Mexico have ensured a reliable supply of low-cost heroin, even in the face of significant increases in user numbers.”
