Applause deserved for this simply excellent resumé of the Andean cocaine sector, including UN and US numbers for Colombia, Peru and Bolivian production. I'm not going to paste any of the charts here because they're better seen all together, but I will indulge by posting PC&B's concluding paragraph as it's one with which I wholeheartedly agree.
"All of these metrics indicate clear failure, despite heavy U.S. and Colombian investment - in money and lives - in a decades-long effort to reduce cocaine supplies coming from Colombia. The argument in favor of a new drug policy could hardly be stronger."
