Two University of Akron graduate students in biomedical engineering have developed a test for traffic stops to determine the amount of active THC in the bloodstream. The two students Mariam Crow and Kathleen Stitzlein won the LaunchTownTM Entrepreneurship Award to receive a $10,000 cash prize provided by the Burton D. Morgan Foundation for their invention and are hoping to market the testing device to states where marijuana use has been legalized.
Nobody should be driving when they are under the influence of marijuana and if this is as accurate as one would expect then this is certainly a good thing. In places where there is a reasonable threshold like 5 nanograms such as in the legal-pot states this could save a lot of time for both police and people being suspected of driving high. For countries where even 1 nanogram can ruin your life this is of course very bad news.
