Crack addicts gather under the Glicerio viaduct in the Liberdade neighborhood of Sao Paulo February 1, 2012. Brazil's surging crack cocaine epidemic prompted officials of Latin America's biggest country to launch a $2.3-billion dollar plan to curb the spread of drug abuse and trafficking by 2014. Crack users dispersed to several parts of Sao Paulo city after military police occupied the area known as "Cracolandia" (crackland). Picture taken February 1, 2012.
