Herbert Hill, a WSU chemist, is part of a team that's hoping to borrow from technology used by airport security screeners and customs agents to detect explosives and drugs to develop a portable device that can test for the presence of THC.
Hill said he and WSU doctoral student Jessica Tufariello are working on a handheld device that uses a technique called ion mobility spectrometry to detect THC in someone’s breath.
Right now, officers and prosecutors rely on blood tests to determine how much active THC is present in a driver’s blood. Those test results aren’t immediately available to patrol officers who suspect someone is driving high.
Initiative 502 set 5 nanograms of active THC per milliliter of blood as the legal limit at which a driver is automatically determined to be impaired.
The test will detect whether THC is present, but won't be able to say at what level.
