I am an RN for 2 yrs now and recently had a nurse claim narcs were missing when she was given meds. It was fine when we counted them after my shift, but she claims the count must have been wrong. I do not do drugs and would not. I worked ten years for my education while being a single parent to three kids, no way would I risk it.They asked me and the nurse prior to my shift to do a drug test. She got hers back yesterday - I am still waiting on mine. I gave them a list of all the supplements I take (vitamins, fish oils etc) and mentioned that I drink some herbal teas. Out of sheer anxiousness I started looking on the net for what could cause false positives on tests. Imagine my surprise that a tea I drink might show a positive test for cocaine!!! OMG!!!The tea I drink is made by Teavana - a chain of premium tea stores. It is called "My Morning Mate" and is touted to have as much caffeine as coffee but with less jitteriness. I found this and several articles about Mate Teas: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1725048/pdf/v039p00e37.pdfI am so scared about coming up positive because of this tea. Has anyone else drank this tea?
