This is the method i use for snorting the "new" now old OxyContin OP pills (20mg, 40mg and 80mg).
1. Remove the slow release coating with an abrasive. I tried several things like a file, cheese grater, a fingernail dremel, but the best was 120-grit sandpaper. Do NOT wet the coating by trying to suck or wipe it off. Only an abrasive will work. Sandpaper worked best for me.
2. After removing the time-release coating, put the pill on the middle of a flat glass plate, then put that plate in the middle of your microwave.
3. Now, cook the pill in the microwave. Cooking times vary on pill size and the power of your particular microwave. For me, for an OP 80, I cooked the pill for ONE minute. Then I cook it again for one minute. Then again. If you cook the pill too long it will burn and you will be PISSED, trust me lol.
4. The end result you're looking for is a pill that is dark tan/light brown in color. The purpose of doing this is to cook off the binding agents in the OP 80 that make it gel in your sinus cavity. It seems that the darker you cook it, the less the pill gels. Just do not over do it.
5. After the desired color is achieved, take the plate from the microwave (careful, it is hot) and put it on a cloth/ovenmitt in the freezer. The plate may break if you put it directly on the bottom of your freezer due to the sudden change in temperature, so make sure to rest it on the cloth/mitt. Leave it in for about 10 minutes.
6. After the OP returns to room temperature or is no longer soft, remove it from the freezer. Let it sit a couple more minutes.
7. Here is the tedious part. Get a pedegg or cheese grater and start grinding the OP 80 into the smallest pieces that you can. This is hard work but its important and certainly worth it.
8. Take the "powder" or mini chunks and snort the shit out of it.
9. Enjoy the high from all of your hard work!
