Citywide Drug Test

WASHINGTON (AP) -- Researchers have figured out a way to give entire communities a drug test. All they need is a teaspoon of wastewater from a city sewer plant.

Oregon State University scientists have already tested the wastewater in ten U.S. cities for remnants of drugs, both legal and illegal, They were able get a snapshot of what people are taking. One researcher calls it "community urinalysis."

The testing isn't designed to point to any one person as a drug user. But, it could help law enforcement and other agencies track the spread of dangerous drugs, like methamphetamines, across the country.

The lead researcher says one city with a lot of gambling showed high levels of methamphetamine while a smaller locale showed virtually none.

By the way, caffeine is by far the most consumed substance in America.
