Cannabis consumption, commerce, and control in global history, from the nineteenth century to the present day. This book gathers together authors from the new wave of cannabis histories that has emerged in recent decades. It offers case studies from Africa, Asia, the Americas, Europe, and the Middle East. It does so to trace a global history of the plant and its preparations, arguing that Western colonialism shaped and disseminated ideas in the nineteenth century that came to drive the international control regimes of the twentieth. More recently, the emergence of commercial interests in cannabis has been central to the challenges that have undermined that cannabis consensus. Throughout, the determination of people around the world to consume substances made from the plant has defied efforts to stamp them out and often transformed the politics and cultures of using them. These texts also suggest that globalization might have a cannabis history. The migration of consumers, the clandestine networks established to supply them, and international cooperation on control may have driven much of the inter-connectedness that is a key feature of the contemporary world.
