Every year the United Nations Office on Drugs and Crime publishes a report with lots of fascinating data on the production and consumption of illegal drugs around the world. This year's report highlights a few interesting trends: despite all the effort put into the war on drugs, the street price of cocaine in Europe has dropped relentlessly over the past two decades (even adjusting for inflation and impurity).

The numbers we have picked out below show the variations in price between a selection of different countries, as well as consumption per person in those places.
