A Reference Handbook examines the production, consumption, and regulation of the Cannabis plant; the plant's commercial, recreational, medicinal, and religious applications; and the various attempts to regulate the production and consumption of marijuana in the United States and other parts of the world. Additionally, it provides a detailed history of the role of marijuana in society, an even-handed presentation of the arguments for and against its legalization or decriminalization, and a comprehensive list of print and electronic resources that can be used for further research on the topic. As contention over the use of marijuana for recreational and medical purposes continues to be at the forefront of public policy debates and more U.S. states consider ballots to allow the production and consumption of marijuana under various conditions, this book will provide students and general readers with invaluable context to understand the underlying issues associated with recent efforts to change marijuana's legal status.
