<p>I didn’t find any particularly reputable sources on worldwide pharmaceutical trade revenues, but [2007</a> World Pharmaceutical Market](<a href=“http://www.chinaccm.com/4S/4S40/4S4001/news/20061122/115701.asp]2007”>http://www.chinaccm.com/4S/4S40/4S4001/news/20061122/115701.asp) seems to suggest it’s somewhere near $550 billion/year.</p>
<p>As for your assertion of regular MDMA adulteration of marijuana… I’d love to see a reputable source to back that up. Not to be blunt, but I suspect you’re the victim of some third-hand stories.</p>
