Abstract:
Summary The compositions of waterpipe tobaccos available for retail sale on the US market are relatively unknown compared with more popular products such as cigarettes. Indeed, the phrase “waterpipe tobaccos” is used only in some governmental regulations and in journal articles dealing with regulatory aspects of those products. Commercially, the terms “shisha”, “hookah tobaccos”, and “flavored tobaccos” are used. In addition to the differences in commercial terminology, there is also confusion about the composition of such tobaccos, with the term “waterpipe tobacco” also being applied to produ

Abstract:
AbstractSmoking, especially cigarette smoking, is the most common form of tobacco consumption world-wide. It is generally accepted that smoking carries health risks for smokers. The combustion and pyrolysis products of tobacco generated during smoking are considered to be responsible for the harmful effects. Smokeless tobacco, another wide-spread form of tobacco use, is not subjected to burning and produces no combustion or pyrolysis products. Therefore, there is an increasingly intense debate about the potential role of smokeless tobacco in reducing the harm of tobacco use.An overview is pres

Abstract:
Tobacco farming has emerged as an important concern for tobacco control advocates. Tobacco-growing countries face unique and important challenges to comprehensive, intersectoral tobacco control. These challenges stem from narratives that position tobacco as an important driver of economic growth and development, perpetuated by tobacco interests with close ties to government decision-making. While the global tobacco control movement has enshrined a commitment to alternatives to tobacco growing, there remain numerous obstacles. Tobacco growing is often situated in contexts with limited markets f

Abstract:
Tomato spotted wilt virus (TSWV) is economically prominent disease for its impact on tobacco (Nicotiana tabacum L.) production worldwide. An increase of the incidence of symptoms typical of TSWV has been observed in tobacco production areas in Denizli province of Turkey where tobacco is significantly grown. Surveys were conducted to determine the prevalence status of TSWV in tobacco cultivars and its possible sources of infections in four tobacco growing districts of Denizli province. A total of 501 plant samples from field-grown tobaccos, weeds, potential intermediate hosts, seedlings and see

Abstract:
Theories on tobacco addiction divide into two camps, the exposure orientation and the adaptive orientation. The exposure orientation suggests that the use of tobacco is addictive because of the reinforcement properties of tobacco or because of tobacco's biochemical-altering effects. The adaptive orientation views tobacco addiction as a functional response to distress and, therefore, a form of sub-optimal adaptive behavior. Though the two views are not mutually exclusive, the case is made that the primary cause of addiction is explained by the adaptive orientation, and not the exposure orientat
