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.
