Don't understand ?: Amphetamine false positives on screening tests are highly common, and if such a test is used for "forensic" purposes - i.e., there are legal consequences to a positive test - a confirmatory test should be used that will tell a false from true positive. If you are on decongestants of any kind, false + results are common, and other drugs may cause them as well. You can insist on confirmatory tests.
