Is the Recession increasing drug use?

In a recent study reported on by the BBC 95% of the dollar bills in DC have traces of cocaine on them and other major cities in America have similar numbers. This is up 20% form two years ago, the reason is thought to be due to people turning to drugs to get away from the stress of the recession.



I can't help but to think that if this is true and the reason drug use is up right now is due to the poor economy, then really the best thing for these people to do is to take the money they spend on drugs and spend them in other parts of the economy we could get a nice little boost. thought I guess even if the money is going into the black market it will end up in the main economy eventually (drug dealers do buy things)
