European cities’ sewer water exposes use of cocaine, cannabis, meth and ecstasy
Imagine you could let your city urinate in a cup and submit the sample to a laboratory for drug testing. Would it pass?
Researchers in Europe did something similar with 42 major cities, and many of them failed.
Lab tests on sewage water to detect chemicals excreted after drug use turned up high levels of cannabis, cocaine, ecstasy, meth and other amphetamines.
