I hate the idea of snorting anything, so that wouldn't work for me.
My doc's father is an anesthesiologist and was addicted to opiates for a long time, which I think is the original reason he got registered to dispense, and why he's so caring - he did give me subutex for a while when he had to prescribe me oxycontin - I have degenerative disc disease - and I admit, I shot 'em. It took, like, three 3cc syringes for each pill, but yeah. It didn't do much, tho I think that has more to do with the fact that I WAS TAKING OXYCONTIN. Duh. And of course I slammed the oxys too, I'm a junkie and always will be, and IV being my ROA of choice, I always, always give in and then hate myself for it b/c no script EVER lasts. IV you get maybe 4 hours, instead of 12 if taken properly. I have no idea why he insists on this, but he tells me anytime he has to prescribe me other opiates, to take my suboxone with it. (I think he caught on w/ the subutex, so that's history. So are the OCs, sadly.)
Right now, tho, I have been without anything for weeks, and believe me bupe w/d lasts much longer than anything else i've gone through, and I'm thinking that without anything in my system, the naloxone wouldn't do a damn thing to stop the bupe if I slammed it. I long ago realized that it was the bupe keeping me from getting anything out of other opiates, not the naloxone - that shit's out of your system in 4 hours. Confirmed by the anesthesiologist who assisted my C-section. Trust me, it's the bupe - it's like a 400-pound bouncer manning the door of the mu receptor.
However, before I ran off and loaded up a needle, I'd probably look up the BA of naloxone vs bupe through IV administration. I know it's like, nonexistent sublingually, while bupe has a high BA that route. Conversely, if you swallow the pills the BA of the *bupe* is almost nonexistent. *shrug*
I've been thinking about just coming clean w/ my doc about my needle addiction, b/c I think he'd understand. He's a fucking hippie, man - long gray ponytail, drives a Stanza, gave me his cell and pager numbers. He has twice given me a Demerol shot when I came into his office with what he calls "shake and bake" - DT's or whatever they are. AND he's never charged me for a visit. If heaven exists, he's going there when he dies.
I digress. I do that. I guess I should answer the question - I usually just put them under my tongue. It's not so bad for me, except when I was pregnant and had morning sickness from hell. I probably would shoot them if I didn't take them on a daily basis. I'd be afraid the naloxone WOULD knock me back, badly, with shit in my system.
Pls forgive long rant, or feel free to tl;dr.
