As cocaine consumption falls in the United States, South American drug traffickers have begun to pioneer a new soft target for their product: big and increasingly affluent Brazil.
And the source of the cocaine is increasingly Bolivia, a landlocked country that shares a 2,100-mile border with Brazil.
