Brazilian authorities are considering a law which would make treatment compulsory for crack cocaine users in Rio de Janeiro, ahead of the 2014 football World Cup.
With many users smoking openly on the streets, Brazil has the highest rate of crack cocaine consumption in the world.
But the World Cup and the 2016 Olympics have prompted officials to attempt a clean-up, with treatment being seen as the best way to tackle the problem.
