Does marijuana stay in the root of the hair follicle for 6 months, or does it get pushed out by the new hair growing in?

Does marijuana stay in the root of the hair follicle for 6 months, or does it get pushed out by the new hair growing in?

Long time: Thc is stored in fat cells which serve as a reservoir and release it slowly into the bloodstream and from there into hair follicles. For a long time user, the "reservoir" can be quite full and so may feed follicles at 6 mo and longer. The new hair growing out takes some follicle thc with it as new thc is being fed in. ...Read more

I smoke marijuana one time about 35 days ago I have a hair follicle test in two day should I pass?

Probably: The best information I can find to answer this is from the website of NORML (who should know), which states that, while a hair follicle test can be positive for months in regular users, it is "doubtful" that it would be positive after a single use.

Would I pass a THC hair follicle test if I smoked marijuana once. It was once in July and I won't have the test until at least the end of October?

Possibly no: The hair follicle test is standardized to collect a specimen dating back about 90 days. Depending on how fast your hair grows, you could possibly test negative if a specimen close to the scalp is obtained. ...Read more

If my boyfriend smokes marijuana around me on a daily basis for a year and even while I sleep will I fail a hair follicle test in a couple days?

If my boyfriend smokes marijuana around me on a daily basis for a year and even while I sleep will I fail a hair follicle test in a couple days?

Probably you're ok: The reports I've heard suggest that you will pass. There is a small worry that if you were in a very non-ventilated space w/ it for a long time - some may show, but read this: http://www.homehealthtesting.com/blog/2010/06/does-second-hand-marijuana-smoke-show-up-on-a-drug-test/ I think they will be reassuring to you. ...Read more

If i smoked marijuana once and had a hair follicle test 109 days out will i pass? I would estimate that i smoked about 1/2 a joint

If i smoked marijuana once and had a hair follicle test 109 days out will i pass? I would estimate that i smoked about 1/2 a joint

Unlikely: Thc is stored in fat cells which serve as a reservoir and release it slowly into the bloodstream and from there into hair follicles. For a long time user, the "reservoir" can be quite full and so may feed follicles at 6 mo and longer. The new hair growing out takes some follicle thc with it as new thc is being fed in. From 1/2 joint very little will be stored. ...Read more

I dont ever smoke marijuana. But i took one hit from a joint 2 weeks ago. I have to take a hair follicle drug test in 4 days. will i pass it ?

I dont ever smoke marijuana. But i took one hit from a joint 2 weeks ago. I have to take a hair follicle drug test in 4 days. will i pass it ?

Hard to say: Hair testing is very powerful (1pg/mg) and reflects drug use over the past 90 days (depending on the length of hair available). A shaved head or razor cut might remove evidence of activity from 2 weeks ago. One hit may be too little to worry about, but I can't say I know. If it's very important - you might want to tell them the truth. This sounds like an unintended outcome if you're being honest. ...Read more
