Alright so the thing is I have IV'd Opana 40mg before without taking off the coating first or any preparation beyond crushing the pill up well in water prior to injection. There is usually a lot of powder left which I assume is a result of the extended release coating, however that powder is still usable and acts as kind of just a big wash in a way to me. So my question is: Since I've been fine using this method and gotten satisfactory results, is there any substantial reason not to IV Opana this way?
