Oxycodone aka Eukodal is not a &quot;preform&quot; of heroin, period. Hydrocodone, aka Vicodin, has nothing to do with heroin either. This is seriously bad drug information. they&#x27;re just opiates.<p>If you don&#x27;t know, now you know. Nothing I dislike more than bad drug information being passed off as researched fact.
