I smoked 3 hits of crack 50 days ago and I have a hair drug test that was brought to my attention. Will I pass? I was stupid and made a bad decision

Why are you taking the test ?
Family services?
Probation?
Job interview?

What is the cut off limit, is there any tolerance?

Normally, for most tests this will not show up since it is so minor about.

I would say the small amount would be undetectable, if that was the only usage/dosage in the past 90 days from the test date.
