Article Photos: Brazil debates treatment options in crack epidemic 20/20

In this photo taken Dec. 21, 2012, former soldier Bobo pushes his cart containing recyclables he collected at a slum in Rio de Janeiro, Brazil. 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.
