The Defense Department is actively fighting the war on drugs. It’s one of its top missions, but the only way to have a chance in winning it is to have the cooperation of other countries.

The Defense Department is the lead organization working to stop drug flow by air and sea. Needless to say, a major player in this drug war is Mexico. A recently published DoD report provides some insight and key updates on the efforts of the U.S. and Mexico as they try to stem the flow of illegal drugs.

Cartels in Mexico are able to produce large amounts of drugs due to the lack of restrictions and regulations on chemicals. With these chemicals, cartels are able to manufacture fentanyl, methamphetamine, and other dangerous drugs.

According to Mathew J. Flynn, the Deputy Assistant Secretary of Defense for Counternarcotics and Global Threats, “Mexico remains the source of nearly all heroin seized in the United States and is a transit route for much of the cocaine available in our country.”
