A pregnant crack dealer counts her money on a street in Sao Paulo March 18, 2012. Demand for cocaine has soared along with the economy over the past decade and fueled an abundant supply of crack now ensnaring thousands of new addicts. With nowhere else to go, legions of the addicted roam city centers across Brazil, many of them venues chosen to showcase Brazil's ascendance during the 2014 World Cup and the Olympic Games of 2016.
