Will Nyquil Show Up On An Alcohol Test?

Yes it will, as nyquil has some alcohol on it. It wont be much, but if you are worrying about it you are probably on probation or something where you have to report. I work at a treatment center, and it does happen. So if that is your case, pick up one that says alcohol free on the label

Thank you how about a urine test?
