Marijuana is cultivated in nearly every region of the world, from the jungles of Laos to the arid hills of northern California. It's smoked and enjoyed for medicinal, spiritual, and recreational purposes by an estimated 200 million people worldwide. In Pot Planet, journalist Brian Preston sets out on a global ganja safari to explore strange new cannabis cultures, to seek out new growers, activists, and other reefer revolutionaries . and to boldly get baked with each of them. Preston's journeys take him across every strata of pot cultivation and enjoyment. In the Canadian Kootenays he meets hemp farmers struggling to harvest their crop on the fringes of legitimacy. In Cambodia and Morocco he explores the final frontiers of Third World weed enthusiasts. In northern California he takes a clear-eyed look at the medicinal marijuana movement, seeing both its promises and its problems.

In England, Switzerland, and Spain he observes grudging governments catching up to public tolerance. And at the Cannabis Cup in Amsterdam he joins in the raucous multiday tasting competition and celebration at the international summit of the best breeders, growers, and connoisseurs in the world. Part investigative travelogue, part cultural history, part polemic for the unfettered enjoyment of nature's most perfect and pleasing herb, Pot Planet is an unforgettable odyssey into the multifaceted world of hemp, full of wit, insight, and inspiration.
