Are you getting the the OP 80s or the old school 80's? BIG DIFFERENCE!! If they are the new OP's I would probably stick with the roxy 30's. much less filler and a lot more flexibility. You can break the new OP's down, with the oven/microwave method but I have never tried it.. As soon as they switched to the op's I switched to opanas (one of my top ten moves of all time ) If you want to take them whole then the op 80s are usually ok. I have heard that sometimes they don't totally disolve in the 12 hours and it cause stomach aches, etc. Even if I had the old school 80's I think that I would still prefer the roxys.. I know a lot of people smoke old school oc's but don't ask me why, to me its the biggest waste of all time.. honestly, if you don't shoot them (good idea not too) then eating them is the best way. you get about 60-70 percent of the oxycodone in your system compared to about 40 percent snorting.. eating them, you wont get that initial rush, but it will stay with you for a long time. Iving you will get 100 percent of the drug into your system, but its not a good idea to shoot pills at all. If you must, please use a wheel filter or at least cotton filter the shit out of them.
