I took these products for week and a half before i took a drug test. Sudafed was from behind counter and this was taken twice a day.
Can sudafed, and inhaler, and nyquil make you test positive for meth on a urine test?

I am almost sure, sud can have false result on methaphe
Pseudoephedrine which is the active ingredient in Sudafed and other cold products (and now has to be bought from the pharmacy counter because it is a product they use in the production of methamphetamine and carries limits on the quantities that are bought) can sometimes cause a positive for methamphetamine on urine drug screens. A more sensitive test like GC-MS test can confirm a false positive. The more sensitive tests can detect the difference in pseudoephedrine and methamphetamine.
