The Flow of drugs from Mexico to the United States has been a source of trouble in US-Mexican relations for at least two decades. The dominant view in Mexico is that the problem arises from the inability of the United States to control its domestic demand for heroin, cocaine, and marijuana. The dominant US view has been that the Mexican government has failed to make effective efforts to control the supply of drugs. At times — in particular after the killing of Enrique Camarena, an agent of the Drug Enforcement Administration (DEA), in 1985 — US government anger at Mexico's alleged failure to maintain the integrity of its anti-drug efforts has been the dominant source of friction between the two nations.
