"Cocaine use is now so widespread that everyone in Britain is carrying around traces of the drug – on their banknotes.
A study of cash from around the country has revealed that 99.9 per cent of all banknotes now carry traces of the class A drug, a level only previously seen in cocaine hotspots such as London.
The research, by forensic scientists at the Bristol-based company Mass Spec Analytical, showed that even currency circulating in rural areas is almost always contaminated with the drug."
