Book Description
Cannabis: Evolution and Ethnobotany is a comprehensive, interdisciplinary exploration of the natural origins and early evolution of this famous plant, highlighting its historic role in the development of human societies. Cannabis has long been prized for the strong and durable fiber in its stalks, its edible and oil-rich seeds, and the psychoactive and medicinal compounds produced by its female flowers. The culturally valuable and often irreplaceable goods derived from cannabis deeply influenced the commercial, medical, ritual, and religious practices of cultures throughout the ages, and human desire for these commodities directed the evolution of the plant toward its contemporary varieties. As interest in cannabis grows and public debate over its many uses rises, this book will help us understand why humanity continues to rely on this plant and adapts it to suit our needs.

Book Description
For thousands of years, Cannabis sativa, commonly called cannabis or marijuana, has been used for many different purposes. Due to its enormous medicinal values, increasing numbers of countries and regions have started to legalise the cultivation of this plant. When grown commercially, cannabis is most often produced in controlled environments including greenhouse and indoor growing rooms, to ensure consistent growth and high quality. Even for field production, propagation is frequently conducted in controlled environments. Commercial operations and individual growers who cultivate cannabis for personal consumption, require scientific information on how to cultivate cannabis most effectively and efficiently. To meet these needs, scientists have been conducting research on how to optimize cannabis cultivation both in small and large scales. Handbook of Cannabis Production in Controlled Environments is the result of collaborations between some leading cannabis scientists and highly experienced practitioners. Featuring full-color illustrations and photographs throughout, this book covers a broad range of topics include cannabis biology; science and techniques for breeding and propagation; management and optimization of both aerial and rootzone environments; plant nutrition and nutrient disorder diagnosis; crop training and pest management; harvesting and post-harvest processing. Along with the basic aspects of controlled environment cannabis production, this book summarises developments in these areas that may challenge old beliefs and improve production. Led by Editor, Youbin Zheng, President of the Canadian Society for Horticultural Science/La Société Canadienne de Science Horticole, this book is a practical guide for cultivators, consultants, and researchers; a reference for students; and an information source for individuals who grow cannabis for personal consumption.

Book Description
Cannabis sativa is best known as the source of marijuana, the world’s most widely consumed illicit recreational drug. However, the plant is also extremely useful as a source of stem fiber, edible seed oil, and medicinal compounds, all of which are undergoing extremely promising research, technological applications, and business investment. Indeed, despite its capacity for harm as a recreational drug, cannabis has phenomenal potential for providing new products to benefit society and for generating extensive employment and huge profits. Misguided policies, until recently, have prevented legitimate research on the beneficial properties of cannabis, but there is now an explosion of societal, scientific, and political support to reappraise and remove some of the barriers to usage. Unfortunately, there is also a corresponding dearth of objective analysis. Towards redressing the limitation of information, Cannabis: A Complete Guide is a comprehensive reference summarizing botanical, business, chemical, ecological, genetic, historical, horticultural, legal, and medical considerations that are critical for the wise advancement and management of cannabis in its various forms. This book documents both the risks and benefits of what is indisputably one of the world’s most important species. The conflicting claims for medicinal virtues and toxicological vices are examined, based mainly on the most recent authoritative scientific reviews. The attempt is made consistently to reflect majority scientific opinion, although many aspects of cannabis are controversial. Aside from the relevance to specialists, the general public should find the presentation attractive because of the huge interest today in marijuana. Unfortunately, society has become so specialized and compartmentalized that most people have limited appreciation of the importance of science to their lives, except when a topic like marijuana becomes sensationalized. This review of cannabis can serve as a vehicle for public education in the realm of science and technology. Indeed, towards the goal of disseminating the important information in this book to a wide audience, the presentation is user-friendly, concise, and well-illustrated in the hope that non-specialists will find the topics both informative and entertaining.

Book Description
Over the course of a year, in just one national forest in California, raids on illegal marijuana growing operations yielded 19,710 pounds of infrastructure, 138 ounces of restricted poisons, 4,595 pounds of fertilizer, 12 gallons of common pesticides, 5.6 miles of waterlines, and 102 propane bottles. Even as efforts to legalize marijuana accelerate, such “trespass grows” spread exponentially—as does their effect on the environment. The nature of this impact on the land and in the political arena is the pressing issue addressed in Where There’s Smoke. This first-of-its-kind interdisciplinary anthology draws on the insights of scientists, researchers, and activists and ranges across the humanities, natural sciences, and social sciences to explore the troubling environmental consequences of illegal marijuana production on public, private, and tribal lands. Classified as a Schedule 1 drug, marijuana has been a central focus of the so-called War on Drugs—with the perverse result of shifting marijuana production from Mexico to the United States and with unanticipated consequences for the natural environment. Where There’s Smoke assesses the broad spectrum of the policy’s effect on land and water, flora and fauna, as well as the firsthand challenges faced by those tasked with responding to this tangled and often dangerous state of affairs. In its broad scope, varied perspective, and depth of detail, the book will prove essential to an understanding of the complex social and environmental ramifications of marijuana policy and politics in the United States.

Book Description
The medical use of marijuana is surrounded by a cloud of social, political, and religious controversy, which obscures the facts that should be considered in the debate. This book summarizes what we know about marijuana from evidence-based medicineâ€"the harm it may do and the relief it may bring to patients. The book helps the reader understand not only what science has to say about medical marijuana but also the logic behind the scientific conclusions. Marijuana and Medicine addresses the science base and the therapeutic effects of marijuana use for medical conditions such as glaucoma and multiple sclerosis. It covers marijuana's mechanism of action, acute and chronic effects on health and behavior, potential adverse effects, efficacy of different delivery systems, analysis of the data about marijuana as a gateway drug, and the prospects for developing cannabinoid drugs. The book evaluates how well marijuana meets accepted standards for medicine and considers the conclusions of other blue-ribbon panels. Full of useful facts, this volume will be important to anyone interested in informed debate about the medical use of marijuana: advocates and opponents as well as policymakers, regulators, and health care providers.

Book Description
Evolutionary Ecology of Weeds is the story of WHAT, WHY and HOW some plant species invade and occupy habitats ripe for exploitation. The nature of weeds is the evolution of adaptive traits for seizing and exploiting locally available opportunity. Weeds are the consequence of human disturbance which creates opportunity spacetime, leaving unused resources eager for invasion by weeds. The nature of weeds is the story of us, humans. We created highly successful wild-crop-weed complexes that resist control. We created them by channeling natural selection, the driver of biological change. Plants invade by dispersing, colonizing, reproducing and enduring in a locality. Weeds possess mating systems that generate variable genotypes and phenotypes that struggle for existence, the winners take all. Evolution occurs. Adaptation in weed life history is about timing: timing is everything. Adaptation in local plant communities is interference and facilitation animating strategic roles guided by functional traits. Weed community dynamics is community assembly and ecological succession. Complex adaptive weed system formation reveals larger forces of nature: emergent behavior, physical information remembered. Knowledge of weeds is discovered, then represented in several different ways: ecological demography, life history traits. Representation is confounded by the humans that make them, their beliefs, values and models. Case histories of three weeds explain these concepts: velvetleaf (Abutilon theophrasti), triazine resistant rapeseed (Brassica napus), and the foxtails (Setaria species-group). UNIT 1: THE NATURE OF WEEDS UNIT 2: THE EVOLUTION OF WEED POPULATIONS UNIT 3: ADAPTATION IN WEED LIFE HISTORY UNIT 4: ADAPTATION IN LOCAL PLANT COMMUNITIES UNIT 5: COMPLEX ADAPTIVE WEED SYSTEMS UNIT 6: REPRESENTATION OF WEED BIOLOGY UNIT 7: WEED CASE HISTORY

Book Description
The place of cannabis in global drug prohibition is in crisis, opening up new directions for socially engaged cannabis research. The Routledge Handbook of Post-Prohibition Cannabis Research invites readers to explore new landscapes of cannabis research under conditions of legalization with, not after, prohibition: "post-prohibition." The chapters are organized into five multidisciplinary sections: Governance, Public Health, Markets and Society, Ecology and the Environment, and Culture and Social Change. Case studies from the United States, Uruguay, Morocco, and the United Kingdom show readers alternative ways of thinking about human–cannabis relationships that move beyond questions of legality and illegality. Representing a cross-section of cannabis scholarship, the contributors provide readers with critical perspectives on legalization that are not based upon orthodoxies of prohibition. While legalization signals a global shift in the legitimacy of cannabis research, this collection identifies openings for academics, policy makers, and the public interested in ending the drug war, as well as a way to address broader social problems evident in the age of neoliberal governance within which prohibition has been entangled.
