How Long Does Marijuana Stay In Your Hair Follicles
Can amphetamines such as Vyvanse (lisdexamfetamine) make marijuana less visible in a hair folicle test? I am prescribed Vyvanse (lisdexamfetamine)
Depends on use.: It depends on how often you use it. If you used it only once it can be detected by blood for 12-24 hours while it is detected in urine from 1-7 days. With regular use it can be detected in blood for 2-7 days and in urine anywhere from 1-100 days even if a heavy user. Age, height, weight, metabolism all are considered factors. ...Read moreSee 1 more doctor answer
I have an upcoming drug test, how long does marijuana (thc) stay in your hair follicles? An is there anything to take it out of your system?
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 smoked marijuana seldom in small doses am 5'10 150 pds my hair grows slow and the last usage was 12/16/13 can I be clean for a hair follicle by 3/12?
Hopefully...: The reason you have a good chance of testing clean is that you use it seldom in small doses and have now abstained for a few months. Based on this the odds are good you will test clean but there are no guarantees. I feel such testing in an intrusive invasion of privacy. See http://www.Canorml. Org/healthfacts/testing. Tips. Html good luck! ...Read moreSee 1 more doctor answer
I took an of marijuana two weeks ago and prior to that I took a few hits about a month ago. I'm taking a hair follicle test next week will I pass?
Have abstained from drugs 30+ days, have a hair follicle test, was a light but daily user of marijuana (1 gram per 6 days), what are my chances?
Depends: Hair grows at varying rates among different racial groups. The average is about a half inch per month. If your hair is more than a half inch long they will likely find traces of drug along the shaft if the test is specific enough. ...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?
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/

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 to 2 joint very little will be stored. ...Read more
Can I pass a hair follicle test after two months clean from marijuana? I was a heavy user, have a fast metabolism and thick black hair.
Smoked marijuana in jun2013 for 5 days and twice in Oct2013. I have to take a drug test in a week. Can it be detected in urine or hair follicle test?
If the amounts were huge in Oct, the hair test at a very fine cut-off might nab you. Not likely. Here's a link. http://marijuana.com/drug-test/detection-time/
Stay clean since it matters. Good luck. Perhaps someday this will be a thing of the past. One can hope. Till then, one must be smart. ...Read more
I don't 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
