percocets and oxycontin have the same chemical - oxycodone. The only difference is oxycontin has more oxycodone, no APAP, and is continuous release. 6 10mg percs would be 60mg oxycodone.
percodan and percocet yes are chemically the same as oxycontin they bolth have oxycodone has the main opiate,But thats about it for there similarities. Taking a OC crushed up, or snorted or IV is so much of a different high then eating per's its hits you so much harder and stronger. So watch out they are the same drug but with OC's 9/10 you do them different then you would Per'c, Per's have tons and tons of binders and fillers and oc's don't. As for taking it to get high if you are snorting it start of with sniffing a little bit then go from there until you feel nice. Don't over do it eather, Oding is quit easy so make sure you do it smart don't go and blow the whole pill in one line go out drinking or mixing other downers after you take etc.
yeah with how 'spensive oc's tend to be, the most efficient way to do them is incremental sniffing. It's even better when you space out the times you have some, to get your tolerance back down. For example, take two days off before finishing the pill. oc's are like expensive fire: when small and contained they are good and helpful, but when liberally used, everything burns up before you know it.
