According to the DEA, “The illegal drug market in the United States is one of the most profitable in the world. As such, it attracts the most ruthless, sophisticated, and aggressive drug traffickers. Public Safety agencies face an enormous challenge in protecting the country's borders. Each year, according to the U.S. Customs Service, 60 million people enter the United States on more than 675,000 commercial and private flights. Another 6 million come by sea and 370 million by land. In addition, 116 million vehicles cross the land borders with Canada and Mexico. More than 90,000 merchant and passenger ships dock at U.S. ports. These ships carry more than 9 million shipping containers and 400 million tons of cargo. Another 157,000 smaller vessels visit our many coastal towns. Amid this voluminous trade, drug traffickers conceal cocaine, heroin, marijuana, MDMA, and methamphetamine shipments for distribution in U.S. neighborhoods.”
