The BA for plugging Dilauded is roughly the same as oral. They are right around 30%, while around 50% insufflated. If you wanna insufflate it you'll get more bang for your buck (I'm biased though because I only inssufalte since I switched over from opana). If you don't then just do the conversion from the chart. I prefer the Dilaudid over oxy any day, and I prefer everything about it moreso than the other.
