How can you pass a hair drug test?
even if you shave your head, if they really want a sample, they will go elsewhere on your body. you would have to shave your whole body, including your eyebrows, and I think then they will know you are trying to hide something. as far as switching out the samples, impossible cause they seal the sample in a tamper resistant package. they will know if it is opened by someone other than someone at the lab.
Intercept the hair sample and replace it with someone else's. Most testing is sent off to a lab, and for whatever reason, lab pickups are usually just left right out where anyone can get hold of them (like mail).
set yourself on fire? I think if you have used recently... your SOL. this is a great site to research it though... if there is a way, it will be here: www.erowid.com
