Drug Test question...How far back can a hair test detect Marajuana usage.?

And what if a person only smoked one hit off a joint 3 months ago? Are they looking for a certain level of THC?

the test looks only for the presence of THC, not how much or how little. And the hair will show this for up to a year.

if the hair is being tested, the drugs stay there forever.
