I bet these can be shot like the teva MS Contin generics,I bet it's a similar time release.
I know you dont shoot,but do a test:
Get a spoon,fill with 1.5 ml's of water,and drop a tiny fraction of the pill in.hold a lighter under neath,the pill should gel,and the gel should float to the surface as it starts to boil.
If it does do this,add the rest of the pill.Hold the lighter under the spoon again until the gel forms into a clump and floats to the surface,the water does need to boil,you wont waste much,your not boiling it long.
now take a tooth pick,or even your snorting straw and push the gel to the side.let the liquid cool.put the straw in and snort the resulting solution through a cut drinking straw.you can also add a little more water to the gel,cook it again and snort that solution too.after a second cook,eat the gel.
This is me assuming the Teva ER mechanism for the oxycodone pills are the same as their morphine formulations,which are easy to get around,even for IV use.
If they gel like name brand Purdue MS Contin(which I had today fuck!)then its gonna be a little trickier.you'll have to add a little more water and filter it through a cotton bud into a big 3 ml oral syringe.might have to snort a little more water but it will help break down the time release some.
Hope this helps.
