Researchers at Washington State University are working on a breath test to determine if a driver is under the influence of marijuana…Law enforcement officers have a test for alcohol, but they don't have a tool to test for marijuana impairment. Right now, officers use blood tests to determine if THC is present in a driver's blood.
But WSU chemistry professor Herbert Hill said existing technologies like those used by airport security agents to detect drugs and explosives can be altered to test breath for THC. Hill said he hopes to start testing on humans in early 2015. The Washington State Patrol says it welcomes anything that gets impaired drivers off the road. [One might argue that a little pot might lower blood pressure and reduce road rage in America's big city traffic hell. Just kidding, I think.]
