What do you think would be found if scientists drug tested your entire city?
Oregon State University scientists tested 10 unnamed American cities for drug use by sampling their wastewater.
The test is conducted very simply; nearly every legal and illicit drug that people take leaves the body. Think of it as a community urinalysis.
One moderately affluent community scored low for illicit drugs… except for cocaine. And now we know why they’re called “recreational drugs”: Cocaine and ecstasy tended to peak on weekends and drop in usage on weekdays. Meth and prescription drugs were pretty steady all week, though.
Not a shocker: The ingredient Americans consume and excrete the most is caffeine.
