A new study has shown that up to 90 percent of paper money in the United States is tainted with traces of cocaine.

Banknotes from countries including the United States, Canada, Brazil, China and Japan were tested and scientists have found "alarming" evidence of cocaine use in many areas, with U.S and Canadian currency reported with the highest levels with an average contamination rate of between 85 and 90 percent.

Oh so now all addicts have to do is sniff their cash everytime they want to get high! Good news for them, not such great news for the government.
