I don't know if I can agree with you on this one. My job would be tons easier if anyone could walk into a drug store and buy Vicodin, that's for sure. I think the concern is more for drug interactions, dosage safety and public safety, not just access to narcotics. Similarly, people who think they have high cholesterol can't just go and buy a prescription for Vitorin. If people have legitimate reasons for using Oxycontin or Vicodin, most physicians are willing to supply patients with these when needed.
Are you speaking from a reference of personl experience, or just in general?
