Hmmm.....not the average tripe, a bit worse. Don't inject pills unless you know how to do it correctly and safely as possible (and, yes, you are not).
In respect to buprenorphine; I know first hand that physicians here are making a killing off these suboxone products. These are physicians who have little to no experience in this field.
The 8-hour online test to get a DATA waiver from SAMHSA, which is all that is needed to prescribe this drug (if you don't have board certification in pain management or addiction etc) is a fucking joke. Ive taken it, and it is nonsense. There is an option to take it in person, but i believe the only offering was somewhere in Florida.
Methadone (far too regulated, perhaps the most controlled of the C-II's) is, in my humble opinion a superior drug for the comprehensive treatment of opioid addiction. Maintenance, not detox, seems to work the best (even with buprenorphine formulations). Yes you can die from methadone overdose, and it happens with some regularity. You can also get quite "high" on methadone, and though it takes long to hit peak, it stays at there for a while, and has the nodding properties of other full-agonist (not like IV morphine, fentanyl, heroin etc).
I have played with suboxone without a physical addiction to anything, tried various routes short of injecting and the only effect I got was at day 3, apparently a build of plasma levels or something mediated by the drugs pharmacokinetics.
Snorting, the most "effective" manner I attempted (again only on day 2.5-3; by then I had taken 32mg, mainly intranasal ). Started at 2mg, intranasal. Nothing, 4,6,8,12,16 etc, only at around 16mg did I feel a some MOR activation, and it wasn't especially enjoyable. When I hit peak plasma at day 3 there was a little CNS depression, but was offset by some thebainish like CNS stimulation. Snorting suboxone did give me a headache however, perhaps attributable to the antagonist, I honestly don't know as I did not snort subutex to compare.
I have injected the old style "buprenex" ampules (only .3mg each), but this was many years ago and I was very opioid tolerant. It perceived to have little effect, no true precipitated withdrawal. Strangely enough, the similarly old tramadol ampules (forgot the dosing/amp) DID precipitate WD.
Yes, taking suboxone is better than being an IV heroin user, but from what I've seen, the withdrawal is harder to titrate down than pure agonists like less "potent" but pure agonists; namely methadone.
Warning, never attempt what Ive done, because it, theoretically would kill most of you (in actually, who knows).
Again, methadone is technically more dangerous because you can die from it alone (opiate naive) or even overdose on a semi-tolerant individual (usually polydrug overdose is observed). At 380mg (no, not the starting dose, it was started at 40mg and I kept on demanding more; it was a very expensive and liberal clinic for exclusive people) I felt good, perhaps too good, but hey, it worked. And getting off was not that bad, and you hit acute when you drop to zero, and yes its protracted, but no especially severe. I felt no where near overdose, but I could simply be an outlier in this case. I eventook benzos with it, not even close to over dose. Ive taken nearly a GRAM of methadone (yes, with 10mg tablets, by the handfull). Sure, it put me in a semi-conscious but rather deep nod for a good 6-7 hours consecutively. I think its ok for patients to feel good.
Too bad opioids are feared by physicians, and from what i've seen, its out of fear of liability or DEA troubles, not whats best for the patient. I say move them all to C-IV and put benzos in C-II.
In certain parts of the EU they are pretty liberal, but still, the CYA behavior remains rampant among physicians, especially in the US. Australia is quite strict, but at least they sell codeine OTC.
