Cannabis, one of humanity’s first domesticated plants, has been utilized for spiritual, therapeutic, recreational and even punitive reasons for thousands of years. Humans have excellent practical knowledge of the uses of cannabis, yet limited understanding of its sociocultural consequences, past or present, due to its widespread prohibition. In Cannabis Chris Duvall explores the cultural history and geography of humanity’s most widely distributed crop, which supplies both hemp and marijuana. This book focuses on the plant’s currently most valuable product, the psychoactive drug marijuana, and at the same time provides a global view of the plant, with coverage of little-studied regions including Africa and Australia.
