Waste water analysis using urinary biomarkers allows the reliable detection of actual drug consumption in cities. For the first time, a wide group of scientists have carried out a comparative study regarding the consumption of illegal drugs in 19 European cities, four of which are Spanish, based on waste water analysis. In the case of Spain, cannabis and cocaine consumption is higher than that of other drugs such as methamphetamines and ecstasy, appearing in each of the four cities analysed: Barcelona, Castelló de la Plana, Santiago de Compostela and Valencia.
