Hmm very worrisome it sounds that some places are now doing GC-MS screens instead of antibody screens. That would be much more expensive but more accurate (damn bastards).

I would be worried if I were you and I am worried for myself. I have taken numerous test and always quit for a month before and never ever failed. But I think they all were EMIT/ELISA type antibody screens and then GC-MS to confirm positives from antibody tests. Going straight to GC-MS is scary since it has higher sensitivity.

Lizka do you mean 31 days of not smoking??
Because to think you would be clean after 31 days of smoking is crazy.

I think it is clear you cant trust the home drug test they dont have the sensitivity of lab test be it GC-MS or antibody based screens.
