Heart of Dankness: Underground Botanists, Outlaw Farmers, and the Race for the Cannabis Cup

Smith takes us on a trip-mind-blowing and humorous-deep into the international underground where super-high-grade marijuana is developed, produced, sold, and entered into the Super Bowl of the marijuana world, Amsterdam's Cannabis Cup. Moving between California, the hub of the legalization and decriminalization debate, and the Cannabis Cup in Amsterdam, Smith infiltrates a world where science, nature, and the sometimes criminal intersect.
