Actually hair sample testing is becoming more common. It is a sure and efficient way to tell if some people have been exposed to drugs. (around or using) I highly doubt that the process will ever stand for job positions, but for people who are on probation, it will work great. Only because the people on probation are not supposed to be around or using drugs. That can tell the law officials what they've been doing after being free. On the other hand, places that hire can't really use this test sufficiently because who is to say that someone else was smoking it at a family gathering, and you seriously didn't know it was pot? The hair sample testing could be used to determine other smokeless drugs... so it could be used. I don't know, this could become controversial.
