Researchers at Washington State University are working on a breathalyzer to be used by the Washington State Patrol in determining if someone is “under the influence” of Cannabis.  Law enforcement in Washington, and elsewhere, must currently use blood tests to determine if THC is present in a driver’s blood. But WSU chemistry professor Herbert Hill says existing technologies like those used by airport security agents to detect drugs and explosives could be altered to test breath for THC. Hill claims his team hopes to begin human trials early next year. The Washington State Patrol says it welcomes anything that gets impaired drivers off the road.
