Being Clean and Sober and going to College

After seeing The Anonymous People yesterday, in the documentary was a part about Teenagers that may be in Recovery and how going off to college could be a potential relapse. This makes total sense and something I have never really thought about because after all I am just a wee past my college years. I ended up doing some research on this and actually found about 20 or so different "Sober" colleges and I was surprised to find some well known colleges.
So what exactly is a "Clean and Sober College"?
Well it is exactly what it sounds like. A college where college aged students can go to learn and live in a substance free enviorment.
