Yeah, do that^. I always got good effects from swallowing Oxy vs snorting. Last time I came across it, last year sometime, I sniffed a whole 30mg and I still didn't feel as right as about 45mg Hydros would get me.
The first time I did Oxy though, I ate half a 30, and sniffed the other half and I was GOOD. And that was literally right after a big plate of spaghetti, so how the fuck It worked so well is beyond me....of course my tolerance was a lot lower back then, so there's that.
But if you do insist on snorting some, eat half or 2/3s first, WAIT at least 30 minutes, then sniff. This way you'll get a pretty good dose at once. If you snort it first, then eat more, it's gonna be all gradual and shit and not hit you hard. You want it all getting in your bloodstream simultaneously, regardless of how you take it.
IME though Oxy, and MOST OPIOIDS besides maybe Dilaudid, and Oxymorphone are better eaten than snorted. IDK why, IME though, not only do most opiates not work as well via insufflation, but snorting them also REALLY fucks up my nose/sinuses.
Idk if it's related to the histamine release or what, but almost all opiates fuck up my nose when snorted....like they don't burn at all, nice and smooth usually, but the next day it's like snot-nose central, lol.
You don't need no CWE with 20mg oxy, even if it's Percocet. Just take it, and if you wanna snort a line, break off a chunk before you do...but not if it's a combination product like Percs, you don't wanna snort APAP. But you can't go wrong if you eat 15mg and snort 5mg about 15-30minutes after you pop it.
You probably couldn't go wrong eating it all either, so the choice is yours OP, just be safe, use good sense.
And I agree with the first poster who said that the so-called opiate "high" is QUITE subtle, at least in my experience it is....I don't know why people would pick opiates as a RECREATIONAL drug of choice...but I guess a lot do.
