I am a drinker and I don't like the idea of driving drunk so I bought for myself a good breathalyzer that I always use before driving home. I never drive if I'm .08, I wait until I'm below it. However, the booklet states that in order for the breathalyzer to be accurate I cannot have had anything to eat, drink, or smoke for 20 minutes before taking it. This is because most breath analyzing devices will falsely report acetaldehyde as alcohol. Scientists have found acetaldehyde concentrations in the lungs of smokers are far greater than for non-smokers. I was wondering if anyone knew for sure if my e-cigarette fell under those qualificatons or not. I know for most people they'd say I was being silly, but I want to make sure I get an accurate reading. Sometimes it really is a pain in the rear not to vape for 20 minutes, especially if i've got nothing else to do. right now, I don't vape for the 20 minutes just to be safe but was curious if anyone knew a real answer to this question. No judgments or accusations please, just the answer if you know it.
