<i>Do you have any supporting information?</i><p>The parent commenter is overly mood-affiliated, but Eric Schlosser&#x27;s book <i>Reefer Madness: Sex, Drugs, and Cheap Labor in the American Black Market</i> is good on this topic (<a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;Reefer-Madness-Drugs-American-Market&#x2F;dp&#x2F;0618446702?ie=UTF8&amp;tag=thstsst-20&amp;linkCode=as2&amp;camp=1789&amp;creative=390957" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;Reefer-Madness-Drugs-American-Market&#x2F;d...</a>). I don&#x27;t have a copy of it at hand, but making weed and other drugs illegal was wrapped up in racial fear and fears of what become known as counterculture.<p>Wade Davis&#x27;s <i>One River</i> is about many things, including the ways hallucinogens came to the U.S., how they fit many indigenous religions, and why they&#x27;re far more legitimate than the US makes them out to be. It&#x27;s also an adventure story about the exploration of the deep Amazon and other South American rivers.
