Can someone please tell me which has a higher bioavailability, heroin rectal administration vs insufflation. Please show me a number if you can find it I've been looking online for a while have not found anything.
For some opiates, rectal administration has impressive BA numbers, much higher than insufflation. Usually just a step down from injection, and the same or higher as oral BA. I would assume the same goes for heroin, although I could be wrong.
