Well here you seem to say that it is a faint line, but still noticeable... I am confused, so even with a line, as dictated in these home tests, is a negative for these thc tests, or are you saying I would fail an actual test.

Another question, why are we measuring the first void of the day? I certainly wouldn't be giving the tester my first void, it would probably be late in the afternoon. If a test late in the day shows a line, what would prompt a CS/GC test at that point?
