I rubbed a tiny but of coke residue on my gums 12 days prior to taking an armpit hair test (approx one inch) and did a couple lines 95 days prior. Chances of passing?

Why? The recent or older? I thought hair tests were more for frequent and habitual use not a one time minimal exposure

It depends on what the cut off for the test it. If it is low enough it could be a failure. It is meant to show habitual use, but depending on the binge that could be enough to throw you over. Why are you take a drug test? That REALLY comes into play when you look at the limits for the tests.

A hair drug test is meant to show consistent use over time. That small amount of won't show up in a hair drug test. BTW, body hair can give up to a 1 year history regardless of length. Also most labs have gone to a industry standard cutoff level. I don't offer the lowest limits of detection hair drug test any more.

Thanks for the replies. It was for a custody case, they took armpit hair and I passed.

Oh good. You won this time.

If you have a little one whose custody you want, why are you rubbing cocaine on your gums? This seems to, at least the last time I read it, fall under the things not to do in the parenting handbook. I really hope that this is a wake up call for you and you realize what is important and how that can be put at risk by your own self-gratifying habits.
