My own rant on the subject.

I hate that people with legitimate needs for mediciation (like my wife) get treated like criminals because they can't live without the drugs. Every so often my wife goes through a phase where she starts to worry that her pain isn't real and she's just addicted. At that point she'll try reducing her medication drastically and the end up spending the week in bed because of the amount of pain she's heaped on her body.

Living with back pain for the rest of your life is hard enough without adding insult to injury.
