I just had an interview in Vegas, and I will be tested, not sure for what yet. But instead of the traditional piss test, they will be collecting hair samples. How far back does drugs show up in hair samples? Thanks in advance.

Marijuana (THC) is a fat-soluble drug, and does not typically deposit well in hair, causing a high percentage of "false negatives", a negative result in someone who smokes marijuana frequently.

How far does it go back?

Hair testing generally uses 1-1/2 inches of hair, representing about 3 months’ growth (head hair normally grows at about 1/2 inch per month). It is generally accepted that in order to test positive, the drug in question must have been used 3 times or more within the window of the test. After a drug is used, it takes about 7-10 days for the hair containing the drug to grow out of the scalp enough to be cut. Therefore, the hair test will not include drugs used in the week prior to the test. The drug remains in the hair, growing out much the same as hair dye and "dark roots". Eventually that hair containing the drug is cut off with normal haircuts.


-even better, my hair grows hella fast so I cut it once a week...

I shaved my head once a week when I got hair tested few years ago, so they went straight to my armpit hair. And they took a grip too. I asked the ladies what they would've done if I didn't have armpit hair, and they said the next place they go with is your pubes, and if those are gone, they just find as much hair as possible on other parts of your body.
