INDIANAPOLIS (WTHR) — A California company has developed a breathalyzer that aims to detect pot-impaired drivers.

Hounds Lab created the device which detect the amount of THC in a driver's system.

“It’s an incredibly challenging scientific problem to ensure the really, really low concentrations,” Hound Labs CEO Mike Lynn told NBC4.

The device can detect if someone has smoked within the last few hours, Lynn told NBC4.

“A person can have really high THC levels and be impaired, but within a half hour they can have a low THC level and still be impaired,” Co-Director at the Center for Medicinal Cannabis Research Tom Marcott said.

The breathalyzer will be available to law enforcement and for commercial use in winter 2018.
