Just One Teaspoon?

Researchers have figured out how to give an entire community a drug test using just a teaspoon of wastewater from a city’s sewer plant.

Oregon State University scientists tested 10 unnamed American cities for remnants of drugs, both legal and illegal, from wastewater streams. They were able to show that they could get a good snapshot of what people are taking.

The ingredient Americans consume and excrete the most was caffeine, Field said.
