ah yes drugs that increase dopamine in the nucleus accumbens are well known to not feel good or pleasant.
As a matter of fact many drugs that release dopamine are known to be terrible experiences for many users.
I'm not sure why you're trying so hard to argue that fent. has decent euphoria. There are probably 100s of thousands of posts on BL from the mid-2000s into the 2020s of people here complaining about fent and the fact that it's a cold opioid that provides little if any euphoria with highly reduced duration compared to opioids people actually want like oxycodone, morphine, diamorphine, hydrocodone, oxymorphone, hydromorphone and all the other pharma grade and very good street grade heroin we
used to be able to purchase cheaply in America. We have millions of junkies in America that were addicted young when pills were free/cheap and street heroin was rampant, nearly pure, cheap and widely available on the black market. Those of us that lived through the 90s-2000s had easier access to quality opioids than even people that could buy shit like morphine, heroin, and laudanum OTC in the late 1800s-early 1900s.
Hell at one point before 9/11 even refined opium for smoking was so widely available even in my small town that you could purchase it from any weed dealer selling Mexican brick garbage weed. We can't discuss prices but a gram of that fire opium cost less than purchasing a quarter ounce of bap weed back then. But it vanished from the market after 9/11 never to be seen again. Not that it mattered that much because you could get handfuls of oxycodone and other pills out of your parent's medicine cabinet. They were so cheap and common people didn't bother to pick them up if they dropped them on the ground. High schoolers were showing up everyday with sandwhich baggies full of tablets and giving them out to anyone that wanted one.
Some people are odd-balls that find substances like Diphenhydramine euphoric and consume it everyday/every week. I have absolutely no idea why they do it. It's a dysphoric expereince where you think spiders are everywhere and can not tell reality from fantasy. Where you feel like absolute crap for multiple days afterwards. But some people think it's the bomb diggity. Perhaps you're one of those odd-balls except you get your rocks off on fent. somehow.
As an opioid aficionado I won't touch fent even if I'm desperate for a nod and/or in horrible pain. I hate it that much and so does everyone else I knew that was into opioids. I feel very sorry for anyone coming up today that wants to expereince a nod but has access to nothing else. But it's probably for the best. Since I wouldn't wish the hell that is opioid withdrawal on anyone. With things like kratom extracts and kratom itself on the market I do not understand why anyone would willingly seek out fent. either pharma or street sources (and the analogs). I mean something much safer
and more euphoic is
right there being sold openly at every corner smoke shop and sometimes even in gas stations. Not to mention the much higher quality (and cheaper) sources for the same thing on the internet.
If you're going to take opioids your grandparents have laying around you should been going for the forgotten bottle of Tussinex in the cabinet or the "break through pain" pills (hydrocodone, oxycodone) instead of the fent. patches. All of them are much much better. Tussinex is divine. Don't even need chaser. Stuff tastes like candy. Nods for hours. Time release hydrocodone is really great.
But let's get back to OP:
Should OP try getting high off this fent. patch if he's semi-naive to opioids? The answer is a hard
no every time. There is no way he has a tolerance to make it safe. People like me in my heaviest days of use did not have a tolerance to make it safe. People like my friends and I didn't even like the effects of fent. when we did get stupid and try it. I tried it more than once personally. Since I got stuck with a massive 120+mcg gel patch once because I stupidly bought it for someone else who ended up being blackout drunk (and broke) when I showed up to deliver it. The person I sourced it from refused to refund my money or let me trade it for opioids I actually wanted and bought from them daily. Which were the 10mg percocet yellow school bus tablets and the 30mg roxicodones.
So I was stuck with a large patch I did not want and it sat in my drug box for days because I couldn't find anyone willing to buy it. Since everyone hated fent. So eventually, we got curious enough to prick it open with a needle and try some. Everyone hated it and got scared even from that small bit of material I mixed up
very well in a hydrocodone 7.5mg speckleberry tablet we were only using as a way to carry it up our noses (locals snoted Tylenol here all of the time. Don't ask me why).
I got desperate a few days later when supplies of other opioids were exhausted. I tried consuming the gel from that massive patch through several ROAs. All of them were garbage. If I wasn't desperate to not be in withdrawals at the time I would have tossed that shit in the barrel I burned trash in where it belonged. I tried fent. via lolipops at a later date. It was still awful. At least on its own. It did have
some use adding sedation on top of other opioids. But it was way too risky and I knew better than to keep playing with fire.
It wasn't long after this when the matrix patches came out that a good friend of mine died. His girlfriend almost died to. They took the patches OP is describing and placed them in their mouths. They both had heavy tolerances on-par with my own. Since he and I used to sit up all night snorting opioids together while eating handfuls of xanax bars, smoking weed, taking any other downer pill we could get our hands on and chasing all that shit with hard liquor.
One little mistake and he died. Turned blue and died right in the bed laying next to his girlfriend. His elderly Grandmother found them the next morning when they didn't wake up for breakfast. His girlfriend survived somehow but only barely. He was already stiff, blue and cold by the time he was discovered.
They thought if they did it together they'd be safe. That they could pull the patch out of their mouth in time. They had a heavy tolerance and thought there was no way that "weak" patch would be able to make them OD if they took the precaution to dose together and keep an eye on each other. But he died and she should have died (and did die later from guilt).
In other words: it's a horrible idea for OP to attempt taking this substance and you going on about how it's actually worthwile isn't helping matters. I don't care what some paper says about what it does to rats. Rats are not humans. Rats can not communicate what they're feeling to us. All we can do is observe them and make guesses about what they might be feeling. Of course rats would self admin fent after they've been addicted to it. Human junkies are doing it everyday. Waking up feeling like you have the worse flu ever every morning and needing to cop some dope to get well is a horrible feeling. Of course one would feel slightly euphoric after shooting up some fent and making the withdrawal symptoms go away. At least for a few hours. Ask any one of those people and they'll all tell you the same thing: We wish it was morphine, we wish it was heroin, we wish it was literally anything else.
