First Edition. "A revelation of the vast and menacing traffic in narcotic drugs. A vivid travel record of his voyages and explorations penetrating the hell-holes of five continents, the sensational facts he reveals about the sale and use of narcotics are from the direct observation and from information obtained from members of the 'dope ring', from authenticated reports and from inside information. His pictures of the depravity and human wretchedness that result from narcotics are all first-hand. The close connection between drugs and white slavery and prostitution is exposed."
