This Is Cannabis by Nick Brownlee

Without preaching about the benefits or drawbacks of marijuana, “This is Cannabis provides straightforward facts about its 4,700 years of cultivation for fiber, food, and medicine; the current debate as to its therapeutic potential; the vast underground commercial success it enjoys; and the uneven laws surrounding its sale, possession, and use. While textbook-like in the breadth of information, the writing has the pace of good journalism and is supplemented with personal stories, pertinent statistics, black-and-white photos, a glossary, and a timeline.
