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.
Tobacco use by adolescents and young adults poses serious concerns. Nearly all adults who have ever smoked daily first tried a cigarette before 26 years of age. Current cigarette use among adults is highest among persons aged 21 to 25 years. The parts of the brain most responsible for cognitive and psychosocial maturity continue to develop and change through young adulthood, and adolescent brains are uniquely vulnerable to the effects of nicotine. At the request of the U.S. Food and Drug Administration, Public Health Implications of Raising the Minimum Age of Legal Access to Tobacco Products considers the likely public health impact of raising the minimum age for purchasing tobacco products. The report reviews the existing literature on tobacco use patterns, developmental biology and psychology, health effects of tobacco use, and the current landscape regarding youth access laws, including minimum age laws and their enforcement. Based on this literature, the report makes conclusions about the likely effect of raising the minimum age to 19, 21, and 25 years on tobacco use initiation. The report also quantifies the accompanying public health outcomes based on findings from two tobacco use simulation models. According to the report, raising the minimum age of legal access to tobacco products, particularly to ages 21 and 25, will lead to substantial reductions in tobacco use, improve the health of Americans across the lifespan, and save lives. Public Health Implications of Raising the Minimum Age of Legal Access to Tobacco Products will be a valuable reference for federal policy makers and state and local health departments and legislators.
This volume utilizes the work initiated and executed under a recent major public health initiative, the African Tobacco Situational Analyses (ATSA), which was sponsored by the Canadian government's International Development Research Centre (IDRC) with funds from the Bill and Melinda Gates Foundation. The program was conceived to illuminate the factors that will facilitate the reform of major public health policies, particularly, but not limited to, tobacco. The results, presented in this volume, are an important contribution to the literature on global public health and international development, and comprise the most comprehensive evidence-based analysis of tobacco policy in the African region.
The health and economic costs of tobacco use in military and veteran populations are high. In 2007, the Department of Veterans Affairs (VA) and the Department of Defense (DoD) requested that the Institute of Medicine (IOM) make recommendations on how to reduce tobacco initiation and encourage cessation in both military and veteran populations. In its 2009 report, Combating Tobacco in Military and Veteran Populations, the authoring committee concludes that to prevent tobacco initiation and encourage cessation, both DoD and VA should implement comprehensive tobacco-control programs.
This eighty-ninth volume of the IARC Monographs is the third and last of a series on tobacco-related agents. Volume 83 reported on the carcinogenicity of tobacco smoke and involuntary smoking (second-hand smoke or environmental tobacco smoke) (IARC 2004a). Volume 85 summarized the evidence on the carcinogenic risk of chewing betel quid with and without tobacco (IARC 2004b). That volume explored the variety of products chewed in South Asia and other parts of the word that contain areca nut in combination with other ingredients, often including tobacco. In this eighty-ninth volume, the carcinogenic risks associated with the use of smokeless tobacco, including chewing tobacco and snuff, are considered in a first monograph. The second monograph reviews some tobacco-specific nitrosamines. These agents were evaluated earlier in Volume 37 of the Monographs (IARC 1985) and information gathered since that time has been summarized and evaluated.
"I'm embarrassed to say I thought I knew anything substantial about Wisconsin agriculture or its history before I read this book. 'Wisconsin Agriculture' should be required reading in history classes from high school to the collegiate level. It makes me thankful that Jerry Apps has such a sense of commitment to Wisconsin's agricultural heritage--and to getting the story right." --Pam Jahnke, Farm Director, Wisconsin Farm Report Radio Wisconsin has been a farming state from its very beginnings. And though it's long been known as "the Dairy State," it produces much more than cows, milk, and cheese. In fact, Wisconsin is one of the most diverse agricultural states in the nation. The story of farming in Wisconsin is rich and diverse as well, and the threads of that story are related and intertwined. In this long-awaited volume, celebrated rural historian Jerry Apps examines everything from the fundamental influences of landscape and weather to complex matters of ethnic and pioneer settlement patterns, changing technology, agricultural research and education, and government regulations and policies. Along with expected topics, such as the cranberry industry and artisan cheesemaking, "Wisconsin Agriculture" delves into beef cattle and dairy goats, fur farming and Christmas trees, maple syrup and honey, and other specialty crops, including ginseng, hemp, cherries, sugar beets, mint, sphagnum moss, flax, and hops. Apps also explores new and rediscovered farming endeavors, from aquaculture to urban farming to beekeeping, and discusses recent political developments, such as the 2014 Farm Bill and its ramifications. And he looks to the future of farming, contemplating questions of ethical growing practices, food safety, sustainability, and the potential effects of climate change. Featuring first-person accounts from the settlement era to today, along with more than 200 captivating photographs, "Wisconsin Agriculture" breathes life into the facts and figures of 150 years of farming history and provides compelling insights into the state's agricultural past, present, and future.
In 1910, when Olaf F. Larson was born to tenant livestock and tobacco farmers in Rock County, Wisconsin, the original barn still stood on the property. It was filled with artifacts of an earlier time—an ox yoke, a grain cradle, a scythe used to cut hay by hand. But Larson came of age in a brave new world of modern inventions—tractors, trucks, combines, airplanes—that would change farming and rural life forever. When Horses Pulled the Plow is Larson’s account of that rural life in the early twentieth century. He weaves invaluable historical details—including descriptions of farm equipment, crops, and livestock—with wry tales about his family, neighbors, and the one-room schoolhouse he attended, revealing the texture of everyday life in the rural Midwest almost a century ago. This memoir, written by Larson in his ninth decade, provides a wealth of details recalled from an earlier era and an illuminating read for anyone with their own memories of growing up on a farm.
