[Fallguy20]

[COLOR="White"]na, I really dont know if thats how it works[/COLOR]

[QUIZZLE]

hah honestly this isn't me. My buddy's freaking out right now with an interview tomorrow where if he's accepted has to pass a hair test. I've been telling him I think there's no way he'd fail it smoking once like a month and a half ago but he's still been chugging water like crazy.

[jbot]

he'll be ok i think.

[QUIZZLE]

He just got it cut down to like an inch he said and he had it pretty shaggy before.

[jbot]

if u were bald, would they test ur pubes?

If he smoked a month and a half ago, he would have to cut his hair down to at least however much hair he grew in that last month and a half.

Great question...

He's chugging water to get weed out of.....his hair?

[boozehound]

how long it stays in your system (and therefore how long it will be deposited in your hair) depends on a great # of factors, but principally metabolism and body fat % (IK they are correlated). I believe that it detects an average of ~ 3 months.

Here is a somewhat informative FAQ from a tester. 90 days for head hair, 1 year for body hair.

yeah, that was pretty funny. only works for a urine test (by dilution)

[rufuspaul]

I'd ask her.

yes. see the faq I posted

Boozehound had the best advice. Really there's no way to tell, but I would say he's more towards the safe end if he really only did it once, but 4 weeks isn't a lot of time for a follicle test. He could be in trouble.
