Man, I've searched this before and can't find any solid information on the b/a of nasal administration since, I mean, it's not a way morphine
is medically given. But from extensive use of the generic MsContins (the orange one with a boxed "m" and 60 on the back), oral works way better than snorting
. When I first started doing them, I always snorted them. I'd get high, but it wouldn't last that long, it just hit quick. The guy who I was getting them from told me I should be chewing them up and swallowing them. I tried it, and while it took longer to kick in, it got my higher and lasted way longer than snorting them. I've read that the oral bioavailabilty is between 30-50%. That's really not bad. That's the equivalent of 20-30 mg iv from 60 mg oral.
I have no tried rectal but I have shot the Kadians before, that works very well. A 30 mg shot got me high like eating 60-90 mg. But compared to snorting, eating them works waaayyy better.
And I don't know about y'all saying morphine can't be crushed cus I had some m 30s purple ones back in August and they crushed just fine. Yeah they gel if you try to put them in water but from what I understand, using saline will beat the time release and you can shoot them. Have no tried it though. But if generic MsContins can't be crushed, this is brand new and I have not seen nor heard anyone (irl) talk about it. What about the Kadians? Those are just time release balls in a capsule. Those are able to inject if you crush up the beads. I've shot them a couple dozen times.
But you have to remember, when shooting morphine, that it's only soluble to about 60 mg/ml in neutral pH water. So if you're trying to shoot the 100s or 200s, you're going to need more than a 1mL rig. You'll need a 4 or 5 cc rig. If you just use 1 mL rig, you will have a ton of undissolved morphine. That must be kept in mind.
