UPDATE:

Well my test was postponed from Friday until Monday, which was a pretty big stroke of luck. I diluted a bit, but was in job training for the first half of the day and definitely couldn't leave the class to piss every 15 minutes without raising suspicion so I didn't dilute too much. I took B12 to color my piss yellow and sometime around 3pm I pissed in a cup, after having my blood taken as well. NO HAIR TEST!

Anyway...

Like I said, I only smoke around twice a month and I'm a skinny guy with a fast metabolism. Last puff was 9 days before test. A diluted test last tuesday a week ago came back negative and a yellow, first piss in hours test last thursday came back negative. On the second test I decided to get one of those kits that test for multiple drugs. While the THC line came a little later than the other lines (for drugs I DEFINITELY don't do) it was a definite negative with a bold stroke. I'm an anxious guy and I have a lot riding on this job. Should I be worried or can I relax a little? It sucks, I love weed, and while its a completely harmless drug, the culture surrounding it is poison. I hate to be a sellout, but if I pass OR fail, I'm probably going to stop just because I never want to go through a scare like this ever again!
