I'm a bit puzzled by your comment. Are you suggesting that we should have continued to over-prescribe?
From a harm reduction perspective, taking a patient who is, say, addicted to legal oxycodone because they were overprescribed it. Now what do you do from the perspective of what's best for the patient? Is it a good thing that they're addicted to it? No... but is it more harmful to cut them off cold-turkey? Or is it better to help work with them to figure out how to get off it in a way that doesn't result in them seeking out street drugs to handle the withdrawal?
