What I find funny about the drug testing policy is how easy it is to circumvent and the side industry that exists to provide the tools needed to circumvent it.

I could see the same thing happening if employers started requiring social media credentials. An new kind of social network would have an easy differentiator - "Come to our new social network, along with everything else, you can trust us because we give you two logins: a secure login that you keep for yourself and a compromised login that you give to the government and your employer."
