Huge desolate areas between the six Ports of Entry found along the Arizona border provide stealthy smuggling routes for large drug operations, using national parks and Indian reservations to push methamphetamine, cocaine, and other drugs across the border. This border provides an easy route to Phoenix and Tucson, which house large-scale organizations responsible for distributing the drugs throughout the U.S. We have seen a steady increase in the amount of methamphetamine, heroin, cocaine, and marijuana seized, most notably a 79% in cocaine and a 93% in ice methamphetamine.https://www.justice.gov/archive/ndic/pubs40/40381/40381p.pdf There has been more than 416,000 kilograms smuggled through the Tohono O'Odham reservation, as the reservation is very open to allow unimpeded travel for residents on the reservation.
