title: Distribution of cocaine on banknotes in general circulation in England and Wales.
abstract: A study of the quantities of cocaine on banknotes in general circulation was conducted to investigate regional variations across England and Wales. No meaningful support was found for the proposition that there is regional variation in the quantities of cocaine in banknotes in general circulation in England and Wales.
