Quest Diagnostics

I've done my share of drug tests there, but those times i had time to stop smoking for a while.
I was wondering if anyone has ever gone there and done substitution without getting caught?

Thanks dudddeesss

Of course people have subbed at gotten away with it at Quest facilities. The question is, did they get away with it at the facility you are going to?

Doesn't really matter though because most employment drug screens are unobserved. There are established protocols when it comes to drug testing and it should be uniform throughtout. it should but there are always the "rogue" centers that may be asses and some that may be slackers. But these are rare as most foloow set protocols.
