Scottsdale Cocaine Addiction - Paper Currency Usually Has Traces of Cocaine

Scottsdale Cocaine Addiction - Whether you know it or not, you're probably carrying around at least trace amounts of cocaine in your purse or wallet.

According to a new Spanish study, paper currency from around the world is often contaminated with the drug cocaine. Bills in the United States had an average of 28.8 micrograms of cocaine, while some country's bills had as much as 1,300 micrograms.

Of the European countries, Spain's money is the most cocaine-contaminated. Ireland had the least-contaminated currency in Europe.

"These findings should not be surprising, because cocaine and other drugs are traded using cash, which is handled by the same fingers that directly touch the drugs or wrappings," explained the author of the study.
