Absolutely. NyQuil shows up as alcohol, and sometimes other things. I have been taking Ny-Quill for about 3 months and every urine test I took came out positive for alcohol!
I Have Been Taking Nyquil For A Week Straight In Strong Doses Not Overdose Just Strong Will It Show Up In A 80 Hour Urine Test?
Nyquil has been known to cause false positives for Amphetamines, Opiates & Meth. It also has alcohol in it so you may also test positive for alcohol.
