How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.




Marijuana As Medicine?


Book Description

Some people suffer from chronic, debilitating disorders for which no conventional treatment brings relief. Can marijuana ease their symptoms? Would it be breaking the law to turn to marijuana as a medication? There are few sources of objective, scientifically sound advice for people in this situation. Most books about marijuana and medicine attempt to promote the views of advocates or opponents. To fill the gap between these extremes, authors Alison Mack and Janet Joy have extracted critical findings from a recent Institute of Medicine study on this important issue, interpreting them for a general audience. Marijuana As Medicine? provides patientsâ€"as well as the people who care for themâ€"with a foundation for making decisions about their own health care. This empowering volume examines several key points, including: Whether marijuana can relieve a variety of symptoms, including pain, muscle spasticity, nausea, and appetite loss. The dangers of smoking marijuana, as well as the effects of its active chemical components on the immune system and on psychological health. The potential use of marijuana-based medications on symptoms of AIDS, cancer, multiple sclerosis, and several other specific disorders, in comparison with existing treatments. Marijuana As Medicine? introduces readers to the active compounds in marijuana. These include the principal ingredient in Marinol, a legal medication. The authors also discuss the prospects for developing other drugs derived from marijuana's active ingredients. In addition to providing an up-to-date review of the science behind the medical marijuana debate, Mack and Joy also answer common questions about the legal status of marijuana, explaining the conflict between state and federal law regarding its medical use. Intended primarily as an aid to patients and caregivers, this book objectively presents critical information so that it can be used to make responsible health care decisions. Marijuana As Medicine? will also be a valuable resource for policymakers, health care providers, patient counselors, medical faculty and studentsâ€"in short, anyone who wants to learn more about this important issue.

Smokescreen


Book Description

Smokescreen cuts through years of misunderstanding and misdirection to make an impassioned, evidence-based argument for a new era of forest management for the sake of the planet and the human race. Natural fires are as essential as sun and rain in fire-adapted forests, but as humans encroach on wild spaces, fear, arrogance, and greed have shaped the way that people view these regenerative events and given rise to misinformation that threatens whole ecosystems as well as humanity's chances of overcoming the climate crisis. Scientist and activist Chad T. Hanson explains how natural alarm over wildfire has been marshaled to advance corporate and political agendas, notably those of the logging industry. He also shows that, in stark contrast to the fear-driven narrative around these events, contemporary research has demonstrated that forests in the United States, North America, and around the world have a significant deficit of fire. Forest fires, including the largest ones, can create extraordinarily important and rich wildlife habitats as long as they are not subjected to postfire logging. Smokescreen confronts the devastating cost of current policies and practices head-on and ultimately offers a hopeful vision and practical suggestions for the future—one in which both communities and the climate are protected and fires are understood as a natural and necessary force.




The Health Consequences of Involuntary Exposure to Tobacco Smoke


Book Description

This Surgeon General's report returns to the topic of the health effects of involuntary exposure to tobacco smoke. The last comprehensive review of this evidence by the Department of Health and Human Services (DHHS) was in the 1986 Surgeon General's report, The Health Consequences of Involuntary Smoking, published 20 years ago this year. This new report updates the evidence of the harmful effects of involuntary exposure to tobacco smoke. This large body of research findings is captured in an accompanying dynamic database that profiles key epidemiologic findings, and allows the evidence on health effects of exposure to tobacco smoke to be synthesized and updated (following the format of the 2004 report, The Health Consequences of Smoking). The database enables users to explore the data and studies supporting the conclusions in the report. The database is available on the Web site of the Centers for Disease Control and Prevention (CDC) at http://www.cdc.gov/tobacco.




Principles of Fire Behavior and Combustion with Advantage Access


Book Description

Principles of Fire Behavior and Combustion, Fifth Edition with Navigate Advantage Access is the most current and accurate source of fire behavior information available to firefighters and fire science students today. Readers will develop a thorough understanding of the chemical and physical properties of flammable materials and fire, the combustion process, and the latest in suppression and extinguishment.







Public Health Consequences of E-Cigarettes


Book Description

Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.




Handbook of Smoke Control Engineering


Book Description

The Handbook of Smoke Control Engineering extends the tradition of the comprehensive treatment of smoke control technology, including fundamental concepts, smoke control systems, and methods of analysis. The handbook provides information needed for the analysis of design fires, including considerations of sprinklers, shielded fires, and transient fuels. It is also extremely useful for practicing engineers, architects, code officials, researchers, and students. Following the success of Principles of Smoke Management in 2002, this new book incorporates the latest research and advances in smoke control practice. New topics in the handbook are: controls, fire and smoke control in transport tunnels, and full-scale fire testing. For those getting started with the computer models CONTAM and CFAST, there are simplified instructions with examples. This is the first smoke control book with climatic data so that users will have easy-to-use weather data specifically for smoke control design for locations in the U.S., Canada, and throughout the world. Systems discussed in the handbook include those for stairwell pressurization, elevator pressurization, zoned smoke control, and atrium smoke control. The latest smoke control research and most current engineering approaches are also included. Unique to previous smoke control literature, this handbook provides many example calculations to help designers prevent smoke damage.
