Xanax, Klonopin, Ativan and Valium are all dangerously addictive and overprescribed. I myself have been on one of them for almost 10 years, and I'm quite young. I have a prescription and I only take it when I absolutely have to, (PRN). My doctor trusts me not to abuse it, and I think if he felt I were he would pull it immediately.
But most doctors don't seem to give a $#@! if their patients get hooked.
