Thank you for your efforts, that is about how confusing the information I found out was. My friend took this same test a few years back at the same place of employment and said that she wasn't clean longer than months and somehow passed? I still have some hope because they have an allowance at the job even if you test positive on the test. I am also going to request my results if I test positive and act as though I have never done any drugs (I haven't except the herb) and let them know that I have been exposed to smoke from my mother who has a medicinal license for it so hopefully that will help?! Thanks again and I will post the results from the test when I find them out.
