Marijuana breath test under development at WSU

Washington State University chemistry Professor Herbert Hill said existing technologies can be re-purposed to test breath for THC, pot’s psychoactive component, which would be useful to patrol officers who suspect someone is driving high.

A team at Washington State University is working to develop a breath test that could quickly determine whether a driver is under the influence of marijuana.

Law-enforcement officers already use preliminary breath tests in the field to estimate drivers’ blood alcohol content. But no similar portable tool exists to test for marijuana impairment using a breath sample.

Stoned drivers have become an increasing concern since Washington voters legalized recreational use of marijuana in 2012. A quarter of blood samples taken from drivers in 2013, the first full year the initiative was in effect, came back positive for pot.
