Where are you from? In the US I wasn't aware of Purdue, the makers of OxyContin, to allow any other generic manufacturers to make their own versions of the old formula, OC, oxy ERs, like we used to have.. If you are in another country then US, then chances are these are much like the old pre- OP OxyContin, that are able to just be crushed with a card, sniffed, IVed, plugged, etc.. I used to love smoking the old OCs, before Purdue's bitch ass went and turned them into OP, abuse proof plastic shit! And also loved sniffing them, and plugging them.. IV oxy, not so much, it is really not worth it, if you IV! and if you don't, definitely don't start now, just to try doing it with oxy.. Here is what I would do, to get the most out of them, in all honesty.. PLUG THEM! if oral and sniffing wont work, plug them, and you will get the instanteous onset, very close to IV... but may take 3-5 mins longer to kick in, but it will hit you hard! and last longer than sniffing for sure, obviously not as long as orally taking it whole will, as its an ER, but definitely will be nice! I can almost guarantee, if done right, you wont ever want to sniff oxy again! Plus plugging, is totally harmless, much like taking it orally, it wont harm you at all... compared to injecting, smoking, or sniffing. What I used to do, with MY OCs was, if I had 80s, I would usually sniff or plug half, and smoke the other half on foil, like H.. it ran perfect down the foil, and worked amazing, with the coating taken off first of course! despite what lots of people say about this ROA, smoking oxy works, and gives a nice powerful, instant rush.. but it is dangerously addicting, and isn't good for you, so I wouldn't advise you to do it, especially if you don't already have any kind of experience or habit of smoking heroin or other things off of foil, it is a very addicting ROA with oxy and other opioids/opiates, like H or fentanyl.. I don't even know why I mentioned this, it is not a good idea to start smoking oxy... too addicting, a lot like smoking crack is, but only with the high of oxy! not cocaine! don't do this, I was just saying I USED TO DO IT, when I had access to the old crushable OCs.. Sniff 40mg/Plug 40mg, then smoke 40mg... sniffed and plugged for the longer lasting buzz, and smoked for the quick powerful high... if I were you, I would just plug it.. safest and at the same time, one of, if not the most efficient ROAs with oxy! that is my suggestion to you.. don't follow my footsteps, smoking will lead you to a very nasty addiction, if you end up liking it like I did.. take it from me, and just plug it.. way better than oral or sniffing, at least for recreational value of Oxy ERs... and from an HR stand point, its the best too.
