&gt; But maybe heroin wasn&#x27;t common in Germany and therefore oxycodone was pre- in Germany?<p>Heroin was first marketed by Bayer, a German pharmaceutical company in 1898. That&#x27;s where the name &#x27;heroin&#x27; comes from so oxycodone was definitely not pre- in Germany.<p>Now, in nazi Germany, opium and products derived from it might have been harder to come by because of import sanctions (that&#x27;s why methadone, a fully synthetic opioid, was developed in Germany in 1937). But that would apply to oxycodone just as much as heroin.<p>So no, the author is just full of shit and trying to impress his uninformed readers.
