After arriving from South Asia approximately a thousand years ago, cannabis quickly spread throughout the African continent. European accounts of cannabis in Africa—often fictionalized and reliant upon racial stereotypes—shaped widespread myths about the plant and were used to depict the continent as a cultural backwater and Africans as predisposed to drug use. These myths continue to influence contemporary thinking about cannabis. In The African Roots of Marijuana, Chris S. Duvall corrects common misconceptions while providing an authoritative history of cannabis as it flowed into, throughout, and out of Africa. Duvall shows how preexisting smoking cultures in Africa transformed the plant into a fast-acting and easily dosed drug and how it later became linked with global capitalism and the slave trade. People often used cannabis to cope with oppressive working conditions under colonialism, as a recreational drug, and in religious and political movements. This expansive look at Africa's importance to the development of human knowledge about marijuana will challenge everything readers thought they knew about one of the world's most ubiquitous plants.

OG Kush. Sour Diesel. Wax, shatter, and vapes. Marijuana has come a long way since its seedy days in the back parking lots of our culture. So has Howard S. Becker, the eminent sociologist, jazz musician, expert on “deviant” culture, and founding NORML board member. When he published Becoming a Marihuana User more than sixty years ago, hardly anyone paid attention—because few people smoked pot. Decades of Cheech and Chong films, Grateful Dead shows, and Cannabis Cups later, and it’s clear—marijuana isn’t just an established commodity, it’s an entire culture. And that’s just the thing—Becker totally called it: pot has everything to do with culture. It’s not a blight on culture, but a culture itself—in fact, you’ll see in this book the first use of the term “users,” rather than “abusers” or “addicts.” Come along on this short little study—now a famous timestamp in weed studies—and you will be astonished at how relevant it is to us today.
           
Becker doesn’t judge, but neither does he holler for legalization, tell you how to grow it in a hollowed-out dresser, or anything else like that for which there are plenty of other books you can buy. Instead, he looks at marijuana with a clear sociological lens—as a substance that some people enjoy, and that some others have decided none of us should. From there he asks: so how do people decide to get high, and what kind of experience do they have as a result of being part of the marijuana world? What he discovers will bother some, especially those who proselytize the irrefutably stunning effects of the latest strain: chemistry isn’t everything—the important thing about pot is how we interact with it. We learn to be high. We learn to like it. And from there, we teach others, passing the pipe in a circle that begins to resemble a bona fide community, defined by shared norms, values, and definitions just like any other community.
           
All throughout this book, you’ll see the intimate moments when this transformation takes place. You’ll see people doing it for the first time and those with considerable experience. You’ll see the early signs of the truths that have come to define the marijuana experience: that you probably won’t get high at first, that you have to hold the hit in, and that there are other people here who are going to smoke that, too. 

As the movement for legalization of marijuana spreads across the country, it is important to weigh the possible benefits and pitfalls of cannabis use. Cannabis Consulting is both a handbook and a report from the front lines of medical marijuana use. Writing from the perspective of a parent and veteran schoolteacher turned professional cannabis consultant, Ezra Parzybok tells the often-inspiring stories of his practice, where he assists victims of chronic pain, terminal disease, and even conditions such as ADHD. This timely volume was written for patients and families, law enforcement and health professionals, who are trying to make decisions about cannabis during this critical era of transition. It is an honest, clear-eyed exploration of the marijuana debate that looks beyond the hype and disinformation on both sides to chart a new path toward rational and safe use of cannabis.

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 years, federal marijuana prohibition has had a multitude of consequences, but one of the most important is also one of the most overlooked—environmental degradation. Grass Roots argues that the most environmentally negligent farming practices—such as indoor growing—were borne out of prohibition. Now those same practices are continuing under legalization.

Grass Roots uses the history of cannabis as a crop to make sense of its regulation in the present, highlighting current efforts to make the marijuana industry more sustainable. In exploring the agricultural history of cannabis, There are many social and political histories of cannabis, but in considering cannabis as a plant rather than as a drug, Grass Roots offers the only agriculturally focused history to date.

More and more states are legalizing marijuana in some form. Moreover, a majority of the U.S. population is in favor of the drug for recreational use. In the Weeds looks at how our society has become more permissive in the past 150 years—even though marijuana is still considered a Schedule I drug by the American government. 

Sociologists Clayton Mosher and Scott Akins take a deep dive into marijuana policy reform, looking at the incremental developments and the historical, legal, social, and political implications of these changes. They investigate the effects, medicinal applications, and possible harms of marijuana. In the Weeds also considers arguments that youth will be heavy users of legalized cannabis, and shows how “weed” is demonized by exaggerations of the drug’s risks and claims of its lack of medicinal value. Mosher and Akins end their timely and insightful book by tracing the distinct paths to the legalization of recreational marijuana in the United States and other countries as well as discussing what the future of marijuana law holds.
