He thus, humorously, suggests that he is now ready to purchase illegal drugs (this would then be ''meth'') in order to turn it back into a cold medicine (i.e. pseudoephedrine). This would not be safe to do, but may be a reference to this spoof paper: ''[&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;https&lt;/ins&gt;://&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;improbable&lt;/ins&gt;.&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;com/airchives/paperair/volume19/v19i3/Pseudoephedrine.pdf&lt;/ins&gt;/ A Simple and Convenient Synthesis of Pseudoephedrine From N-Methylamphetamine''], a take on the long-going joke about the recent difficulty in obtaining pseudoephedrine, i.e. it is now easier to get your hands on the illegal drug made from it. &amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
