Why am I passionate about this?
I study people-plant relationships from perspectives including ecology, history, cultural studies, and biogeography. Cannabis is certainly the most famous plant I’ve studied. A decade ago I was researching how Africans used an obscure tree in historical Central America, and came across accounts of cannabis use that surprised me. As I dug into cannabis history, I was continually amazed at how little the topic has been researched. It’s a great time to start learning about the plant’s past, because it’s a fresh, new field for professional academics. Cannabis has been portrayed so simplistically for decades, but in reality it’s a complex plant with a complicated history.
Chris' book list on the history of cannabis
Why did Chris love this book?
Two books entitled Grass Roots were published in 2017. I recommend the other one too (by Emily Dufton), but for this list I chose Nick Johnson’s book because it’s less well known. Dufton provides an excellent social history of cannabis in the U.S. Johnson gives us an environmental history of the western U.S. that is remarkable because of its many facets, including migrant labor in the 1920s, indoor horticulture starting in the 1970s, and pollution in national forests in the present. Today’s marijuana is hugely damaging to the environment, and Johnson argues that federal legalization, and the regulation that would accompany it, are necessary to make marijuana sustainable.

Marijuana legalization is unfolding across the American West, but cultivation of the cannabis plant is anything but green. Unregulated outdoor grows are polluting ecosystems, high-powered indoor grows are churning out an excessive carbon footprint, and the controversial crop is becoming an agricultural boon just as the region faces an unprecedented water crisis.
To understand how we got here and how the legal cannabis industry might become more environmentally sustainable, Grass Roots looks at the history of marijuana growing in the American West, from early Mexican American growers on sugar beet farms to today's sophisticated greenhouse gardens. Over the past eighty…
