Washington State University professors are testing prototype THC "Breathalyzers" that could soon be used to detect marijuana on driver's breath.

Researchers say the handheld portable device screens for THC, the chemical in marijuana that makes you high.

Current testing methods aren't the best for figuring out whether someone is under the influence of pot at that exact moment or if they used in recent days or weeks.

Researchers are conducting a second round of testing on the device, with plans for police to be able to use it on the job sometime in 2016

The current device accurately detected THC about 15 out of 30 times and researchers are working to make it more accurate.
