Faces of Crackland

In this March 14, 2015 photo, Andre Oliveira, 32, poses for a portrait in an open-air crack cocaine market, known as a “cracolandia” or crackland, where users can buy crack, and smoke it in plain sight, day or night, in Rio de Janeiro, Brazil. Andre makes a living by collecting discarded, recyclable items on the streets. (AP Photo/Felipe Dana)
