It may not cause you to test positive for Meth, but for a fact I know it makes you test positive for PCP. I had been sick and had been taking Equate Nite Time (generic for NyQuil) for 4 days only 30cc at night before I went to bed because I had been coughing very badly and thats the only thing I could take to sleep, I took a drug test at a new job and tested positive for PCP. So be careful about what you take, be sure to tell them if you have taken anything over the counter, many things we take everyday for colds, allergies, ect, will have you answering a lot of questions and make you look like a fool!!
