Let's correct that and estimate it ourselves: The War on Drugs was launched in 1971, so that's 46 years it's been going on. And the average household size in the US was 2.58 in 2010 and 3.11 in 1971 according to census - let's take the higher number to get a conservative result that is generous to the US. That comes out to $10000/46/3.11 = $69.9 annually per citizen on average. It's a pity they muddled it up by comparing apples to oranges, because it's actually very favorable for Portugal if you compare apples to apples.
