just a wild guess, but if you were wondering if
vaping (even vaping straight pure grain alcohol) would put you near/over the legal driving limit blood alcohol content, then the answer is no way.. you'd have to vape 3-4 of alcohol glass fulls in a short amount of time to get a buzz, and thats a lot if liquid to vape, lol
I dont have a breathalyzer but I'm sure the cheap ones from dealxtreme and other Chinese sources aren't as high quality or accurate as the ones used by law enforcement
