Drugs at music festivals aren't surprising. Scientists did research on the area around the Glastonbury Music Festival in Southwestern England and did find something surprising. They tested the water in a river on the festival grounds and found dangerous levels of MDMA (Molly) and Cocaine. They suspect that the concentrations of the drugs in the Whitelake River is due to public urination. The concentration of MDMA in the weeks following the festival quadrupled.
Environmental scientists say the concentration levels are high enough to endanger the lifecycle of the European eel who lives in the river.
