JJ, I'll see your clotting disorder and raise you a Hepatitis C Outbreak. The post you are referring to points to a Milwaukee Journal Sentinel report about a sharp increase in clotting disorders associated with IV abuse of the ADF version of Opana introduced in 2012.
Now there is an article in Bloomberg which ties Opana to an increase Hepatitis C infections. Again, it has been linked specifically to hardshell ADF mechanism.
Make no mistake about it, in the very near future you will see Endo voluntarily withdraw Opana or they will see it withdrawn by the FDA. It is functionally useless as an ADF while at the same time it is specifically the ADF mechanism which is causing major morbidity.
