Not exactly the kind of news any city wants to be known for:
"...a new study has found that medieval Florence is on the frontline in Italy's cocaine boom.
Researchers tested a mammoth urine sample taken from the sewerage under the city's streets, museums and art galleries over six months that revealed over 12 kilos of cocaine had been snorted, equivalent to more than 482,000 lines, almost one line per Florentine. Sampling also indicated about one kilo of heroin consumption."
That is some strange news in more ways than one - they actually tested the sewage? More of this story from The Guardian.
