ok so i am an occasional smoker, maybe, 2-3 times a week max with sometimes going 2 weeks without smoking. i am planning on getting a job thru my friend but the thing is that they do a hair as well as urine test. now the urine test is no problem but how do i go about passing a hair sample test? and where do they take hair from? i cut my hair roughly once a week down to a 1. do they use body hair?
