How normal are drug tests using hair analysis?

Question

I have to take a drug test next week. It's a non-DOT drug test, meaning they can test your urine, hair, blood, and/or saliva. I tested negative with a urine test that I tried at home, but I am worried about the hair test because they can detect drugs you did 6 months ago. I haven't done any drugs in 3 weeks or so so I am okay with the urine... but how common do companies use hair to detect drugs?

Answer 1

First of all you must share these good drugs with me. if they test your hair your DONE!!!
But they wont for a non-dot so keep the pee pee clean pass the test and then the party is at Larry's house!!!

good luck with the test.

Answer 2

A hair test is not a very common test because it is one of the more expensive drug testing options. Most companies will use a urine sample for a quick relatively accurate response without the added expense.

Answer 3

Its not that common but when they do use hair most go back 3 months...if your urine is clean your blood should be too same with saliva...hair is your only worry...shave your body and they have to urine test you...seriously

Answer 5

hair tests can detect pot for up to 6 months., however if you use the right preventative action , i.e. the proper shampoo, they will not detect squat and hence you will not be fired!!

Answer 6

Not very common as its expensive usually when they are really suspicious about it, which wont happen unless they know you
