Driving While Stoned? Marijuana Breathalyzers Expected to Hit the Street in 2020

Drivers suspected of being high on pot may soon face the same type of roadside breath test cops use to catch drunken drivers, as several firms prepare new devices for the street.
Hound Labs of Oakland expects to have a marijuana breathalyzer ready by the second half of 2020, according to Mike Lynn, a medical doctor and co-founder of Hound Labs. Another firm, SannTek of Canada, also is racing to have a product ready in that timeline.
Both developers also see uses for the devices on job sites to ensure workplace safety.
