Opioids SC Morphine Injection BA?

[JustAnotherBlueLighter]

I know that oral is generally considered less favourable due to its lower BA, whereas IV is the go-to. But I was wondering if, instead of IV, how would general SC injection compare in regards to absorption, effects, and all that, and if anybody has first hand experience?

I found this chart online when searching, which suggests that it's the same as IV administration: https://www.westmidspallcare.co.uk/wmpcp/guide/pain/relative-doses-of-opioids/

If that's the case then SC should be safer, easier, and as effective as IV?

Is it meant for IM, cause if not you’re asking for an abcess. I’ve found plugging morphine the most effective way to use . Even the SR pills , remove the coating, if you use a hose clamp and grind up the pills to a fine powder. , then add to 3-5 ml cold water and squirt it up there you get a really good hit. It’s all about the fine powder.
