Those who consume alcohol and drive are often subjected to roadside stops, breathalyzer tests and stiff penalties if their blood alcohol content exceeds certain limits. Currently, no such test exists for cannabis intoxication, although the substance can impair driving. Now, scientists report a convenient saliva test for cannabis levels that might someday be used at roadside stops. The researchers will present their results today at the American Chemical Society Spring 2020 National Meeting & Exposition.
Did coronavirus mutate from a virus already prevalent in humans or animals or did it originate in a laboratory?
