is there any way cannibas can show up in a urinalysis other than ingestion? . my mother in law is 85 so it's doubtful that she took up smoking without our knowledge.
has her prescribed any prescription medications that may contain cannabis? why were they drug testing your elderly mother anyway? these tests have to be order for a reason; cannabis does not just "show up" on a routine urinalysis. sounds like this young lady got a "willie nelson" contacthigh! just kidding <positive_smiley> it could of been ingested or cannibis oils can enter through skin. i however agree with beth83 its probably a fluke or accident!
