do you think I passed my test today?

[Burnt Toast]

also, it was a quest SAP 10-50/2000 W/NIT test...I believe that one has a 50ng threshold...right?

Yep, 50 ng for THC. The "2000" is the ng threshold for a certain (off-topic) drug which, in order to maintain rule compliance, is not up for any further discussion in the forums.
