Good question no one asks that! Sorry, I couldn't help myself because it does get asked a lot!

If it can be photocopied or photographed and show up, then that is a passing line. Make sure you test with the first void, the dirtiest of the day and thus the worst case scenario.

If a person's body is completely clean and then enjoys a one time high (not 1 hit but a one time high, you common sense and good judgement as to how much is considered "high"), they can usually pass in 5-7 days. You didn't say if you were completely clean or give a longer history but it sounds like you are an infrequent smoker and then smoked 2 hits over the last 2 weeks so you probably are good to go.
