    Not sure if anyone on here will be qualified to answer this but here is a shot. I work 3rd as a professional driver and take 25-50 mg of benadryl to help me fall asleep, does anyone know or has anyone ever heard of benadryl causing a false pos on a drug screen?

    I've heard that it "can" (depending on several factors) show a false positive for pcp, but only in dosages of 400-500 mg per day, so it doesn't appear very likely. Oh, and I am not qualified, but I have heard this.
