Former soldier Bobo leans against a wall after smoking crack in his home at a slum in western Rio de Janeiro, Brazil, Dec. 21, 2012. Bobo spends his day sorting through trash for recyclables to sell. At night, he turns the day's profit into crack. With a boom in crack use over the past decade, Brazilian authorities are struggling to help such users and stop the drug's spread, sparking a debate over the legality and efficiency of forcibly interning users.
