I don't think it's that simple.
If you're going to start doing heroin--which you shouldn't--oxy is a much safer form than street level heroin where you have no idea what you're getting.
Phillip Seymour Hoffman ODed and died because he didn't know what he was getting. Heroin is actually pretty safe, but it destroys your soul and you never really "cure" the addiction. Even still, I'd rather have oxy out there than tar heroin from Mexican drug cartels. And I'd rather spend government resources on something else.
