A boy, who was identified by municipal agents as a suspected crack user, takes a nap at the screening center for minors accused of crimes and drug abuse, in Rio de Janeiro November 13, 2012. The Rio de Janeiro's Social Action Secretariat has approached people showing signs of crack abuse during operations to offer to send them to the shelters as part of the efforts by authorities to end crack use in Rio's slums, including 9 areas known as Cracolandias or cracklands in the city.
