95% of the Washington DC currency is tainted with cocaine

A new -- and strange -- study by the American Chemical Society has just revealed that nine out of 10 pieces -- as in 90% -- of the paper currency sampled around the United States recently contained traces of cocaine -- as in the illegal substance, which binds to the green ink. According to an ACS news release, the scientists studied banknotes from nearly three dozen cities in five countries -- the U.S., Canada, Brazil, Japan and China. The two North American countries showed the worst contamination, averaging between 85% and 90%. Brazil's was 80%. Toronto's was 88%. China (20%) and Japan (12%) had the cleanest bills.
