Driving stoned is stupid, just to get that out of the way, and it’s a crime. But it’s a crime that’s hard to prove; the only way to determine somebody’s amount of THC accurately is through blood or urine tests, which require warrants and can take days to come back. Field sobriety tests don’t work, and THC is found in much smaller concentrations in the bloodstream. However, there’s demand for a good field test, and some buzzkill has claimed to have met it.
Yep, bad news if you suddenly realize you’re out of food: Hound Labs has developed a “2-in-1” breathalyzer that can measure both THC and blood alcohol level. While they haven’t revealed just how it works yet, all you have to do is blow, and the officer can confirm the guy driving 20 miles under the speed limit blasting reggae is in fact high.
That said, though, you might still be sort of off the hook. Almost no research has been done into how much you have to smoke to qualify as “impaired” at a legal level; federal research funding hasn’t caught up to the states’ legalization push yet. That said, though, solve this issue by staying home: Taco Bell delivers now, remember?
