From BBC world news:
The United Nations says the increase in the use of cocaine paste, or paco, in Argentina has risen by 200% in the past couple of years. Other agencies put the figure as high as 500%.
It is simply the case that the consumption of paco is rising so fast in the poor neighbourhoods around Buenos Aires that it is almost impossible to keep track.
What is clear, say the experts, is that urgent action needs to be taken now to prevent the situation spiralling out of control.
