Food and drinks that set off a blow box..?
Hi there, im looking to put a list together of regular food and drink items that may potentially give a false positive for a blow box in case I need to have one put in my vehicle. I have heard there's numerous items that you wouldn't even think of, that could set off a false positive. For example I've been told that energy drinks, twinkies, big macs, sugar-free gum, coffee creamer, etc. could potentially set the system off. I would like to know what food or drinks to avoid (other than the obvious) so I dont get stuck sitting somewhere because of a false reading.
