86 days clean. Will i pass hair follicle test? Also how long till you receive results?

Hard to say: Typically, a hair test goes back 90 days, but it depends on how fast your hair grows. They are looking at 1 1/2 inches of hair, closest to the scalp. Incidentally, you should not avoid it by shaving your head. They would just use some other hair. And if they do, it is pretty obvious that you are trying to hide something. ...Read more

I take 1/2 of a 5mg oxy about 1x a week to help me with my back t play golf. Is this going to prevent me from getting a job with a hair follicle test?

I take 1/2 of a 5mg oxy about 1x a week to help me with my back t play golf.  Is this going to prevent me from getting a job with a hair follicle test?

Shouldn't : As long as this medication is prescribed by your physician -- that is not a reason to exclude you from employment. Be honest with your potential employer and bring the prescription bottle to your drug test so they can verify it. These types of drug tests want to detect illicit drug use or abuse. Hope that helps! ...Read more

Hi yes I take Zoloft (sertraline) and I was wondering if it would show up as benzodiazepines in a hair follicle test the way it would in a urinalysis?

how long will pot show up on a hair follicle test? I smoked once or twice a week for a couple months. I stopped 3 months ago.

"POT": The standard detection window for the hair test is 90 days. Because hair grows about 1.5 inches (3.8 cm) in 90 days, hairs with a length of about 1.5 inches (3.8 cm) are targeted for cutting. Longer hairs will give a longer window of detection. ...Read more

I had a drug test come back positive (swab) for heroine. Can A hair follicle test prove that i have been clean of any substances?

I had a drug test come back  positive (swab)  for  heroine.  Can A hair  follicle test prove  that i have been clean of any  substances?

Not necessarily: The only SPECIFIC test for heroin is a test for its metabolite 6-monoacetylmorphine or 6MAM. I am not sure whether this is available in swab form, but the first thing with ANY positive test on a screening test, such as a urine drug screen or oral fluid swab is to do the confirmatory test. If they have not done that, they are not following procedure. There also needs to be chain-of-custody on it. ...Read more

How long does alcohol stay in hair? (Hair follicle test) And does frequency of use have an effect? I go out for a few drinks one day a week.

How long does alcohol stay in hair? (Hair follicle test) And does frequency of use have an effect? I go out for a few drinks one day a week.

The hair test: can give a "look back" up to 3 months! HOWEVER it is only of use for agencies/employers with ZERO tolerance for alcohol use. IT'S TOO SENSITIVE!!!!! If you drink AT ALL and a potential EMPLOYER is requiring a PRE-PLACEMENT hair test FORGET ABOUT THAT JOB untillyou have had NO alcohol for 90 days!!!!! MY opinion Only Hope it helps!

I had a hair follicle test that showed positive for methamphetamines. The drugs I take are Zoloft, vyvanse, trazadone, and Wellbutrin. Why??

I had a hair follicle test that showed positive for methamphetamines. The drugs I take are Zoloft, vyvanse, trazadone, and Wellbutrin. Why??

Most likely Vyvanse: Vyvanse is a prodrug that is metabolized into amphetamine by its passage through the liver (its chemical name is lisdexamfetamine), so it is not unusual. Wellbutrin is also a very similar molecule to amphetamine, but I am not sure whether it would show up as a positive in a hair follicle test. ...Read more

If I took a few hits from a joint over 14 months ago, will it show up on my hair follicle test? I also have really long hair if that helps.

If I took a  few hits from a joint over 14 months ago, will it show up on my hair follicle test? I also have really long hair if that helps.

Depends: If they check the hair follicle, the test should be negative. But if they check further down the hair shaft, it may be positive. After 14 months a single exposure to marijuana should show up positive at about 17 cm (assuming normal hair growth). If that was the only time your used, hair on either side may be negative. In fact this type of analysis is used to establish history of episodic use. ...Read more

If i took 30 mg of Adderall (dextroamphetamine and racemic amphetamine) and take a hair follicle test in two months, will the Adderall (dextroamphetamine and racemic amphetamine) be comepletely out of my system by then?

Maybe.: If the lab just tests the growing end of the hair follicle, amphetamine may be present up to 90 days. Stimulants are "out of your system" at the end of each day, but they get incorporated into hair and stay there even after you stop taking the medication. Detection in hair then depends on how quickly your hair grows--and which part of it they test. ...Read more
