Coked Up Money?

I just read in Time magazine that 90-percent of U.S. $1 bills have trace amounts of cocaine. According the the study, bills from Washington D.C. carry the most. I'm not sure what this says about our country's cocaine addiction or the way we use our money. But it might be a good reason to wash your hands more often.

Another way of looking at it: If you're into coke highs and you're hard up, you can always go around licking $1 bills.
