it actualy all depends on how long your hair is... if its only an 1/8th on an inch long, it has shit from how ever long its been since your last hair cut... but if your hair is a foot long, it can tell you shit all the way back from yoour last hair cut...
partyguy420 Reviewed by partyguy420 on . Hair drug testing Hi everyone, I am a new member. I have a hair drug test in about a week. I haven't smoked any marijuana in over 4 months. I looked through the discussion boards and I have only found a few threads of people actually answering back if they passed or not after taking the hair test. Before I completely quit 4 months ago, I was a relatively light smoker (maybe once or twice a month). I will be sure and let everyone know how my test turns out, to help others whose situation is similar to mine. Rating: 5
