It is a question that sparked a year and a half of research, and probably many more, on the cannabis plant and its human history. At this point, I can only hypothesize an answer. But that is no longer my main concern, as in the course of my research the entire story of drug plants, with its remarkable evolutionary twists, poetic dichotomies of tragedy and ecstasy, and penultimate truths, bared itself before me as one of the most fascinating stories in the history of evolutionary life. In plants, humans have found nearly everything they need: food, fuel, shelter, fiber, medicine. With plants that provide these in a reasonably efficient manner, humans have formed ancient, reciprocal relationships, in which immobile plants defy the worst of their evolutionary handicaps. They increase and spread their populations rapidly via means of human waste, locomotion, cultivation, and most recently, transportation. This gives them the edge over plants that either produce nothing of benefit to humans—the rare plant indeed—or whose useful qualities have yet to be discovered. Drug plants derive all of these same benefits from humans, yet they provide us not with sustenance but with another extraordinary, if controversial benefit: The coveted shift in consciousness.
