That's a tough call. I cannot say whether or not you are out of the woods. But, when it comes down to it, no news is good news. They won't call you if you pass, but they will call you if you fail. When I took my UA, they said that the answers would be available within twenty-four hours. It's now been over a week, so I'm assuming I'm clear. At this point, all you can really do is hope. But, if it's been over two days, then so far, so good. The longer, the better. Smoking twelve hours before any drug test is always going to be very risky. Even though it doesn't mean a whole lot, my hopes are with you.
