I had this drug test for the vegas strip casino I worked at. They cut some hair (normally off your head, but if there's none there, they go elsewhere), and can find basically anything you've done in a long while.
Some people would shave off all their body hair thinking that would save them only to find they have an even newer test which is like a piece of tape they stick to your skin and then peel off and they somekinda scan on it and so on...Others have tried to fool the hair test with some special shampoo or whatever.... I think the bottom line is if your doing drugs and about to take one of those tests your ****ED!
