Are there any drugs that could interfere with the screening of opiates?

Codeine—a commonly prescribed pain medication and the active ingredient in some prescription cough medicines—and Meperidine are structurally related to morphine so they can cause positive opiates test. In addition, poppy seed bagels or other food containing poppy seeds also cause false positive opiates test if cutoff level of the test is less than 2000 ng/ml.
