How long to pass the hair test??????

I stopped smoking for three and a half months, then took about 8 hits of some potent stuff this past week, and now i've stopped again. How long do you think it will take for me to . . .

pass a hair test?
pass a piss test?

Thanks for your help!!!

I dunno about the piss test, but for a hair test, it will be there as long as your hair is. Your best bet is to cut your hair off, so you won't have any of the hair you did when you smoked.

piss test depends on how much you sweat, what you eat/drink how much you weigh etc etc...
