I've never heard of meth being used for pain control. But oxycontin is very effective, especially because it is time released. Then again you've got the stigma issues, and it's been in the news so much because of thefts from pharmacies and people abusing it. But people have the potential to abuse any pain medication, whether it's oxy or demerol or morphine, so I don't really know why any one would get singled out above and beyond another. It just aggravates everyones' lives who are trying to responsibly manage their pain.
The benefit to the oxy would be there are none of those side effects like spacey-ness or being dizzy or lightheaded, etc. Some of the short-acting pain meds are good for breakthrough pain or accute pain, but when dealing with the chronic pain and management, it's a different monster all together.
It's my opinion that those of us in chronic pain face a lot of potential inaccurate treatment or undertreatment, and that the fears of addiction can be given more attention than the fear of quality of life. A chronic pain sufferer is not addicted, but dependent, just as one would be on insulin or a heart med, -- it's how we function.
I am extremely fortunate in my work with my physician and managing the pain from my back problems, and for that I am thankful. I have seen how difficult it can be, for those on both sides of this battle.
