Best place for a drug test!
This is a hair test only facility, so make sure you have some hair to test. If you are bald like me, they can take a hair sample from your arm or leg. If you don't have hair in these areas, you may have to grow a beard like I did.
If you do have hair, they will take about an inch or so from the back of your head.
The technician who took my sample was very friendly and nice. They don't automatically assume that you are a drug user and give you the third degree like other places (ahem...LabCorp).
Their Web site has a wealth of information if you are nervous about the drug test, but you really have nothing to be scared about.
