False positive: Sometimes taking certain other medications like zoloft (sertraline) (sertaline) or Daypro (oxaprozin) can cause a false positive urine drug screen for benzodiadepines. http://www.ncbi.nlm.nih.gov/pmc/articles/pmc2728940/.

Watch what you eat: As a corollary to Dr. Pappas's statement remember NOT to to put POPPYSEED dressing on a salad you may treat yourself to just before going in to do a drug screening test for your place of employment or local methadone clinic. Then, you have to convince people you're not on opiates!
