Dirty Dollars in Your Wallet?
Believe it or not, there’s likely traces of cocaine in your wallet. It’s on your dollar bills.
Researchers led by Yuegang Zuo, a professor at University of Massachusetts in Dartmouth, analyzed currency in 17 U.S. cities. They discovered that 90% of $1 bills harbored small amounts of cocaine. The currency had such small traces of the drug, so health concerns were not an issue. The bills likely came in contact with cocaine during drug deals or when users handled them.
