I'm not saying opiates addiction isn't a genuine problem, but it's a largely individual one. There's no widespread negative externalities to prescribing opiates to a patient. Antibiotics on the other hand, present a classic limited pool resource allocation problem (the same species of problem as the tragedy of the commons).
It's antibiotics that should require a three part pad, with one copy sent off to the federal government and investigations into over-prescribers -- not painkillers. It's antibiotics that should be subject to intentional treaties governing their distribution and use -- not painkillers. It's antibioatics that should have criminal penalties for misuse -- not painkillers.
