There are mayny sources of pain for which opiates are the best temporary fix. For example, knee replacement.
The number of such patients who become addicted is tiny. What bothers me is the withholding of opiates for cancer patients, especially terminal patients with pain. Since cancer is the end of the road for roughly half of people (and increasing as other causes of final ends are being better treated), withholding pain control for the terminal out of fear of addiction seems deeply wrong to me.
