Can you break down those 10 mg opana er and inject them?

Yes you can, although you should'nt really inject any drug if not done by IV by a doctor or professional health care provider. Opana 10mg (round, pink) you crush up put 50-60cc of water on the broke up pill, stir & mix well into the water. Then you put you cotton in and pull & you're ready to go. If you aren't an IV user do not do this by IV!

Please, please dont do this. Injecting dissolved pills is never a good idea. There are inert ingredients that do not dissolve completely and if injected could could cause a number of problems like infection or inflammation of a blood vessel, or even pulmonary embolism or a stroke which can be and often are fatal. Injecting all of a time release medication can also lead to overdose as you are bypassing the time release mechanism. Any time you chew. break, dissolve or otherwise alter a time release pill, you could be subject to overdose because you can release a fatal dose of medication. If your medicine is not working to relieve your pain, you should speak to your Dr about it or go to the ER for evaluation. Please dont dissolve and inject pills. We dont condone this kind of behavior on this site and we want you to be safe and this is not a safe behavior.
