a hair folicle test in most cases cannot tell how long u have been using but does tell if u have used in the last six months.
hair folicle test are verry un common and inaccurate because if any form of a drug touches your hair it spreads to all hair cells,so say per chance some one was snorting coke on a bus seat b 4 u got on and you sat in that same seat when u got onand your hair touched the coke remains then u would test pos for coke on a hair folicle test
