It ain't just stars, I've personally known a couple of people to die from prescription drugs and I know MANYYY people who are addicted to them. What people need to realize is, just because you're a doctor, doesn't mean you do whats best. Many many many doctors are as corrupt as any drug dealer you'll ever meet.
I knew a doctors who's specialty was Oxycontin and pain meds. All you had to do was make up a BS excuse, pay the $150 visit fee, and you were given 60 pills of 80mg oxycontin and 120 of Vicadin A MONTH! He got busted eventually, but you better believe that, if someone wants it, there's someone willing to sell it to them. And the more money you have, the easier it'll be to get it.
