Will acetaminophen show up positive for anything on a urine test. and if so what will it show up as? also can hydrocodone cause a false-positive for meth on a urine test? i've heard there's a lot of things that can do that.

Urine toxicology: Employers don't usually care if you take acetaminophen or paracetamol. Hydrocodone is an opioid, related to oxycodone, morphine, etc while meth is in amphetamine class, so they won't cross react. However, many common consumer items can cause false-positives so do be careful.
