I know the question has been asked a bunch, but I've been freaking out. I smoked on Nov 22, and had a hair test on April 14. I can't remember the last time I smoked prior to that. Do I have any reason to be worried?
I found some varying information online about hair tests. I'm about 5'11, 170 lbs, and I have very dark, short hair (it's long enough to do a comb over, about an 1.5-2.5 inches long now). I've probably had 2 or 3 haircuts since Nov 22.
Edit: I got my results today, I passed.
