99.9% of British banknotes show traces of cocaine, according to forensic tests conducted by a London newspaper.

Lead researcher Dr James Carter explained: “Once cocaine is fixed on to a note it tends not to come off. The cocaine particles become caught up in the fibres of each banknote.”

Humorously, the newspaper isolated the plummeting cost of cocaine as the reason for this supposed increased usage.

Cocaine must be cheap if users still have a £10 or £20 note left over that they can afford to use solely for consumption.
