Please help docs! is ms contin (morphine) stronger than oxycontin?

No: It's the other way around - oxycodone is 3 to 5 times more potent than morphine, but in equipotent doses, they have the equivalent effect. "strength" is not a characteristic that means better or worse, it's the size of the pill or the shot. When drugs are given in equivalent doses, they work about the same, although there are individual differences in side effects and other characteristics.
