I can't speak for every one, but I had been on oxycodone for 20 some years, then they added oxycontin to the program the last 2 years. You build up a resistance to them. It was at that point I told the doc to get me off of them. It took a couple of years to do it, with the help of my pain specialist. But I've now been off of them for about a year now. If you can live without them. It's much better. But sometimes when you're in pain, you will do anything to make it lessen.
