London has the highest concentration of cocaine in sewage in Europe, research shows.
Experts said the UK capital was slightly ahead of Amsterdam for the amount of the drug in waste water.
The EU’s drug agency said the average daily concentration of cocaine in London sewage was 737mg per 1,000 people in 2014.
This was the highest level found in the analysis of more than 50 cities. However, the capital fell below Amsterdam in the list when taking into account weekend samples only.
The survey showed London had the fourth highest daily concentration of ecstasy.
However, no traces were recorded in the city for the other three drugs tested – cannabis, methamphetamine and amphetamine.
The European Monitoring Centre for Drugs and Drug Addiction said waste water analysis is a ‘rapidly developing scientific discipline with the potential for monitoring real-time population-level trends in illicit drug use.'
