Poppy seed muffins: are a frequent cause for false-positive morphine urine drug screens. Poppy seeds can also be found in salad dressings, and on bagels. A GC/ MS test of your urine can quantify and definitively identify the substances in your urine. A low amount of morphine on the GC/ MS would most likely be from ingestion of poppy seeds. Talk to your physician about these possibilities.
