The main focus of this book is providing evidence on and interpreting the risks associated with heated tobacco products (HTPs) in terms of their health effects and social effects; in addition, the author introduces a harm reduction theory related to HTPs and electronic cigarettes. The book also addresses the history of these products, their marketing strategies, and policy implications. These products are new and the accompanying health risks have yet to be determined. However, since Japan accounts for more than 80% of the world’s market for IQOS, the most popular heated tobacco product, researchers around the globe will be very interested in the outcomes. Written by a leading researcher in the field of tobacco control, Science and Practice for Heated Tobacco Products offers a valuable, unique resource for researchers in the fields of epidemiology, public health, social sciences, addiction, and tobacco research. Since tobacco is associated with a host of diseases including cancers, cardiovascular diseases, diabetes mellitus, and respiratory illnesses, researchers and healthcare workers whose work involves these diseases will find this book both thought provoking and insightful.
