A member asked:

What are some medicine that might come out positive as meth on a drug test medicine i take prometh/codeine, prednisone, advair, hydroxzine. false positive for meth

A doctor has provided 1 answer

None of the above: There are many false positives for all amphetamines, but not specifically methamphetamine. Proper drug testing goes beyond the screening test - if that is positive definitive testing should be done, which will eliminate essentially all false positives. Every cold medication around can give a positive amphetamine, but not a positive for methamphetamine. You need to demand the definitive test.
