I know they do the urine test for smoking and illegal drugs. Does anyone know if they do hair testing as well. I heard hair testing was only for certain "groups" of people.

Hi Ryan,
Yes, hair can be used for drug testing as well. Not sure what you mean by "groups" of people.
The advantage of hair testing, or downfall depending upon how you look at it, is that it can cover a much longer period of time.
