Drug Use World Map
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.
