WASHINGTON - Chances are there's cocaine in your wallet. Researchers looked at 234 bank notes from 17 U.S. cities and found that 90 percent had small traces of the illegal drug. Bills from larger cities, like Baltimore, Boston and Detroit, were among those with the highest average cocaine levels. Salt Lake City had the lowest. Scientists analyzed only $1 bills from Washington and found that most had tiny amounts of cocaine. Yuegang Zuo, a professor at the University of Massachusetts, led the study. Except for Washington, Zuo said he and his colleagues examined a range of denominations, from $1 to $100.
