Everything is shaved except my legs. So I will have to let it grow before I can have the test done.

What I don't quite understand though is this: Say you smoke today and about 3-4 days later the contaminants are done being deposited into your hair, how long would you have to wait to shave the actual contaminated hair off?
I ask because if you have ever plucked a hair from the root they are quite long (sometimes 1/8"), and I would think you would have to wait for that hair to become exposed outside on the surface of the skin before shaving in order to actually get rid of the contaminated hair.

Am I right? If I am right how long would you have to wait to shave that? Would you have to wait 18 days after smoking it?
