A Scientific Breakthrough Brings Us Closer to a Weed Breathalyser

By Chris Mills on at

Law enforcement officers around the US are anxiously waiting on the day when a portable weed breathalyser becomes reality, so they can stop relying on the scientifically dubious roadside munchies test. Thankfully, one Californian company claims to be almost there. (Though the Canadians next door are also on the case too, as we found out back in July.)

Hound Labs has developed what they claim will be the first accurate, portable breath-based device that can detect THC levels. The current ‘driving while stoned’ test relies on a blood draw, and while other companies are also working on pot breathalysers, Hound thinks it will win the race.

The company hasn’t released many details on the technology: it will be accurate down to the picogram of THC, it won’t be able to pick up on weed ingested through edibles, and it should be entering clinical trials next year, in collaboration with UC Berkeley. [Hound Labs via Gizmag]
