The Universe Throws A Curve Ball

So that drug test I was waiting for to start actually working finally came in and it happend to be positive. WHAT? They called me up when I was at work and told me that it was positive. I asked what did I test positive for they didn't know cause it turns out those results are confidential. So I asked what I could do, I was told to call the woman's supervisor and ask to fight the results. So I called up and was told that a medical work up and inquiry would take place. Meanwhile the woman who was incharge of my hiring got an email saying that I had failed my drug test. After I got off the phone my boss and the hiring lady told me that I couldn't stay in the office being that I had failed my test. I was accompanied out of the building by my boss Tim (who was really nice about the whole situation and gave me his views on the subject of drug testing which turned out to be a little more liberal than I had thought) and rode my bike to the train station and thought hard of what I could have tested positive for . Shortly after I got home I got a call from the lab and they proceeded to tell me my lab results. Apparently I had tested positive for morphine use. That's right people morphine use. What the heck!? I now have 72 hours for the doctors to show that it was a false positive. And now the time starts ticking.
