90 percent of dollar bills circulating in the country have traces of cocaine, particularly in large cities like Baltimore, Detroit or Boston, a percentage that rises to 95 per cent for the city of Washington, according to a study presented yesterday to mark Annual Meeting of the American Chemical Society.
The research was conducted by a group of scientists from the University of Massachusetts, who were tested in thirty cities in five countries-the United States, Canada, Brazil, China and Japan - that allowed to the "alarming "evidence that cocaine use is still widespread in many areas.
For U.S. and Canada, the average ticket is contaminated between 85 percent and 90 percent , while in China and Japan is between 12 percent and 20 percent. " To our surprise, we are increasingly finding more and more traces of cocaine on the bills, "said Zuo Yuegang, said university researcher who led the study.
The presence of traces of cocaine in banknotes circulating in the U.S. has increased 20 percent from a similar study conducted two years earlier, when the percentage of paper money "tainted" amounted to 67 percent. "Maybe this increase may be related to the economic crisis, "said Zuo. Scientists for years have found that cocaine may be present on the bills because they" pollute "in the operations of illegal sale of the drug or because the tickets are used by consumers to sniff the "white powder" whose particles are impregnated for life on the bills.
"But in any case one can not be entered by anyone sniffing a dollar bill except it has been previously used by a consumer, "said the researcher." Nor will affect your health and it is very difficult to detect their presence in results the blood and urine tests to detect whether the drug is consumed, "he added.
