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

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?

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

I was wondering how far a hair follicle drug test goes back. Why I was asking was because of a job, someone said they go back 6 months for this job?
