Since police have stormed some of Rio de Janeiro's most dangerous shantytowns to seize back territory long held by a powerful drug dealing organization, hundreds of crack cocaine addicts have moved to other areas, creating new "cracklands."

Health workers make daily rounds, as part of a program run by Rio de Janeiro's Social Action Secretariat, looking for the suspected addicts to remove them from the streets. In the past week, 290 suspected addicts were taken to nearby shelters.
