“A helpful and insightful analysis about the plant. . . . Duvall makes the case that Cannabis is a powerful plant and one that needs to be better understood. He clarifies the confusion over its various names and roles while lending needed ballast to the current conversation. The book brings light to what Duvall calls the shades of meaning in ‘the human-Cannabis relationship, which has unfolded through vast sweeps of space and time.’”

Publishers Weekly

“Clearly written, comprehensive, and rigorously researched, Duvall’s Cannabis is a superb, easily digestable crash course on the history of the remarkably diverse human-Cannabis relationship. As one of the few true scholarly histories of the cannabis plant produced in the last decade, Cannabis clarifies or refutes many of the widely accepted claims about the plant’s origins, dispersal, and history found in a wealth of semi-scholarly works. . . . Brief and highly readable . . . Duvall’s book moves at a brisk and steady pace, riddled with vibrant illustrations and peppered with historical anecdotes integrated so seamlessly that they belie what was surely an excruciating research process. . . . Cannabis is perhaps the most important scholarly work on the plant to date.” 

Hempirical Evidence

“A useful and delightful addition to the world’s library on cannabis. Given that cannabis legalization has emerged as a civil rights issue in our time, I highly recommend it to anyone concerned about the social and political debates concerning this drug today.”
