Drugs use map of the world

The World Drugs report for 2012 is out and it shows that 230 million people around the world - 1 in 20 of us - took illicit drugs in the last year. The report also says that problem drug users, mainly heroin - and cocaine-dependent people number about 27 million, roughly 0.6% of the world adult population. That's 1 in every 200 people. The report is published by the United Nations Office on Drugs and Crime and is full of fascinating stats - we've extracted some of the key ones for you in this visualisation, created by Andy Cotgreave of Tableau.
