But the one that should really perk a few ears up is one line in particular from the article linked by Phil: "As a result [of urine testing versus hair testing], companies don't get an accurate idea of what a driver does in his or her free time."
Wow
I wonder, how far are we from the compliance geeks saying that if you fail a hair test you should be charged with illegal drug use and sent to prison or at least to mandatory rehab. After all, it would be in the interests of public safety, and if just one life is saved, it would be worth it, right?
