Here is the pertinent timeline.

-Day 1: Smoked a small sized bowl of medium grade marijuana for the first time in many months - Abstained for the next couple of weeks
-About 2 weeks later (1/15/06): Smoked a medium sized bowl of medium grade marijuana
-(2/17/06) Had to give a labcorp UA test. However, the program used to relay urine to labcorp was able to convince them to drop the cut off levels from 50nm to 10nm. I am not sure how much this affects its detectability- I have heard rumors of someone taking one or two hits and then taking this same test a week later and clearing it. I had to urinate first thing in the morning, with no flushing or such activity. Labcorp's site says they can detect 1-2 joints approximately 3-5 days after using, but this is at 50nm. What are the chances that my test will be clear

Any ideas here?
