Ecstasy Levels Spike In Rivers Near Major Music Festival

Levels of the illegal drug ecstasy were found to have spiked in rivers near a major music festival in Taiwan that draws more than a half-million revelers annually. Researchers said they're concerned not only about widespread use of the drug at the festival, but its potential effect on aquatic life.

Another study found that the Belgian city of Antwerp had the highest traces of cocaine, amphetamine, cannabis, and ecstasy in sewage of more than 40 European cities tested.
