Leaf of AllahKhat is a quasi legal psychoactive shrub, produced and marketed in the province of Harerge, Ethiopia, and widely consumed throughout Northeast Africa. In the late nineteenth century the main cash crop of Harerge was coffee. Leaf of Allah examines why farming families shifted from cultivating coffee and food crops to growing khat. Demographic, market, and political factors facilitated the emergence of khat as Harerges leading agricultural commodity.
