Hi! I have a pretty important question. I recently went into a drug rehab. Actually 6 months ago. Well, I got out 2 months ago, and a month after that I ended up relapsing, and I took 2 Xanax one day. Well, it's been a month since I took it. Now I have a possible job. The problem is they are doing a hair folicle drug test. I don't know how far this test goes back, and what all it tests for? I did have a script for the Xanax. Would they believe I still had xanax from 6 months ago?
