Mexican drug trafficking groups-sometimes referred to as transnational criminal organizations-dominate the import and distribution of cocaine, fentanyl, heroin, marijuana, and methamphetamine in the United States. Washington has also sought to stem the flow of illegal drugs into the United States by bolstering security along its border. The United States has partnered closely with its southern neighbor in this fight, providing Mexico with billions of dollars to modernize its security forces, reform its judicial system, and make other investments. The country has seen more than three hundred thousand homicides since 2006, when the government declared war on the cartels. Thousands of Mexicans-including politicians, students, and journalists-die in the conflict every year. Mexican authorities have been waging a deadly battle against drug cartels for more than a decade, but with limited success.
