Lol Those kids in Reindeer Spotting were shooting up like 8mg of buprenorphine at a time. I've always wondered why they liked it so much (besides the cost) and if they were really getting 'the nods' at such absurdly high dosages? If they had used smaller dosages, they'd have been able to stretch it out longer. And it would have been more "recreational" with the blood level spikes & drops (one would think anyway).
But yes, buprenorphine was a major DOC in places like Finland and France.
As for OP :
Yes, these two meds can be "recreational" for NON tolerant persons. Although they are not ideal choices for various reason.
And "recreational" can be subjective.
I've seen people throw up and nod out from 0.02mg of buprenorphine.... and they hated it. So was it recreational? I dunno. I think if you're puking and on the verge of passing out every few seconds, whether or not that's 'recreational' is for the individual to interpret.
Potency doesn't always equate to euphoria (which most people seek for recreation). For instance, I find fentanyl (which is 'stronger' than heroin) to lack any euphoria whatsoever. So while it may be more potent, it's certainly not any more enjoyable either. Bupe is similar. It may be 50x more potent than morphine, but it doesn't have the same amount of euphoria. In fact, the 'nods', if you even get them, on buprenorphine are not the euphoric, orgasmic blissful type you get on heroin. Instead they feel more like unchecked dysphoric narcolepsy. And can actually be annoying.
Think of these drugs as more like incredibly potent & strong opioids, with all the side effects of opioids, but none of the fun and much longer acting. Best used for tapering or maintenance. And even then, they're still not perfect.
