Can nyqui cold medicine cause a breathalyzer test to fail
I don't think so unless you take more than your supposed to. It only has 10% alcohol for the whole bottle I think.
Nyqui has alcohol in it and that is why the test failed. Can get hooked on it.
YES! NyQuil can cause you to fail a breathalyzer... Especially if it's one that's installed in a vehicle!
