Don't know about the weed issue, but Costco poppyseed muffins will give a false positive for opiates. I've heard this thousand poppy seed ingestion anecdote before, and it is very much a falsehood. Happened to a good friend at my former carrier. He had to go in and be retested and also had to be examined by a doctor for evidence of needle usage.
Reminds me of a good "contact high" story from a coworker back in the freight days. Good story for another time.
