If you were to pass a marijuana drug screen at the 50ng/ml cutoff, can the lab still do the GC-MS test? I've read contradicting answers everywhere... *Let's also assume that the person being tested did not dilute.
Could they? Yes. Will they? No. If you pass at 50 ng/ml it's safe to say that you are pretty clean. And to the above poster, what don't you get about 50 ng/ml?
