if you smoked meth over a month ago how long does it stay in your system? How would you pass on a hair folical test?
Follicle tests cover periods of up to 90 days, and since hair is dead, inert material, there is no way to cleanse it. Short of completely shaving your body, you cannot fake your way through it.
umm it actually stays on you for a while, it'll be in your hair.. so shave your head balled if your desperate to pass..
