I'm pretty shure those Opana ER's must be shootable as well, I doubt it's actually even that hard to circumvent the time-release mechanism on them. You just need some proper knowledge of chemistry and some creativity.
I think that by letting the crushed up pills, or maybe even the pills whole, dissolve in a glass of acidified water with a pH of 2 (simmilar to stomach acid), they'll slowly give off their dose of Oxymorphone to the acidified water during 12 hours. After 24 hours, all the Oxymorphone should have been given off to the acidified water, after which any remains should be filtered out. Than one has to basify the solution to precipitate the Oxymorphone, filter it through a small filter to obtain the Oxymorphone base. This can then be dissolved in slightly acidified water to get a Oxymorphone HCl solution, for example. Wether this is possible or if it just ruins some perfectly fine pills, I don't know yet, it depends on what kind of gel the pills turns into on contact with water. For the people who have tried dissolving it, did it just turn into a little blob around the size of the pill, or did it turn into a blob the same volume as the water it was added too? MS Contins just turn all the water they're dissolved in, into glue, the more water the you add to this glue, the less viscous it becomes, but it still stays gluey. However, some pills that gellify when coming in contact with water, only turn into a blob of gel around the same size as the pill would be when intact. If it's the case with the Opana ER's as with the latter situation, then it won't be too difficult to extract the Oxymorphone from them, and it will most likely be high yielding as well. When dissolving a crushed and powdered pill in a glass of fairly acidified water of pH 2, the pill should slowly give of all of it's Oxymorphone to the water during the following 12 hours, just like it would when swallowed and dissolved in a human's stomach. Just to be shure, 24 hours are waited before the remains of the pil will be exhausted and can be disposed, as it should have given off all of it's Oxymorphone by that time. After that, the solution could possible be used as it is, depending on it's concentration, or the dissolved Oxymorphone could be precipitated by basifying the solution and letting the solution stand in the fridge for a few hours. After all the Oxymorphone has precipitated, it can be obtained by filtering the solution with a small, double coffeefilter, leaving the pure Oxymorphone behind in the filter. When the filter has dried, the Oxymorphone is scraped of off the filter and dissolved in 10ml of water containing 4-5 drops of 10% hydrochloric acid or 2 drops of 37% hydrochloric acid per 40mg pill. That way, theoretically, one should be left with a clean 10ml solution of 3-4mg/ml Oxymorphone.
