BACKGROUND Previous results proved that simultaneous effect of tobacco smoke constituents and alcohol consumption may change toxicity of these substances and have a greater effect on hepatic and pancreatic disease and cancer risk. The aim of this study was to investigate hepatocyte and pancreatic cells regeneration after tobacco and/or ethanol treatment. METHODS In the study, four groups of r...

Outdoor places, such as parks, remain a source of secondhand smoke (SHS) exposure. We assessed attitudes toward smoke-free parks among U.S. adults. Data came from the 2009-2010 National Adult Tobacco Survey, a landline and cellular telephone survey of noninstitutionalized adults aged ≥18 in the 50 U.S. states and D.C. Descriptive statistics and logistic regression were used to assess the preval...

There is abundant evidence to show that nicotine is the principal addictive component of tobacco smoke. The results of laboratory studies have shown that nicotine has many of the behavioural and neurobiological properties of a drug of dependence. This article focuses on the evidence that nicotine has the rewarding and reinforcing properties typical of an addictive drug and that these properties...

INTRODUCTION Since 2000, local jurisdictions in California have enacted hundreds of policies and ordinances in an effort to protect their citizens from the harmful effects of secondhand smoke. We evaluated strategies used by state-funded local tobacco control programs to enact local smoke-free policies involving outdoor recreational spaces. METHODS The Tobacco Control Evaluation Center analyz...

BACKGROUND Although the negative health consequences of the exposure to second hand tobacco smoke during childhood are already known, evidence on the economic consequences is still rare. The aim of this study was to estimate excess healthcare costs of exposure to tobacco smoke in German children. METHODS The study is based on data from two birth cohort studies of 3,518 children aged 9-11 year...

Passive smoking exposure is a topic of great concern for public health because of its well-known adverse effects on human health (International Agency for Research on Cancer 2004). Two news articles on this topic were published in the February 2011 issue of Environmental Health Perspectives (Burton 2011; Lubick 2011). Lubick (2011) discussed the global health burden of secondhand smoke, and Bur...

This manuscript examines the public policy importance of 1993, United States Department of Health and Human Services actions to require doctors and hospitals to report a new external cause of injury code or E-code for environmental tobacco smoke related to causes of death such as lung cancer and severe heart disease. Methods included a qualitative archival analysis of all previously internal to...

We used an improved method for trapping carbon-centered radicals (.R) from the gas-phase to compare radical suites trapped from various tobacco smoke and model smoke systems. Using a nitroxide trap, 3-amino-2,2,5,5-tetramethyl-1-pyrrolidinyloxy (3AP), on solid support, we trapped radicals directly from the gas phase, washed them off the support, and analyzed them with HPLC. Separation of the tr...

Four-month-old female Wistar rats were exposed for 20 days to tobacco smoke obtained from non-filter cigarettes. During the exposure, concentration of tobacco smoke was monitored indirectly by measuring the CO level (1500 mg/m3 air). The efficacy of exposure was assessed by measuring urine nicotine and cotinine levels. Cigarette smoke did not change total cytochrome P450 and b5 protein levels i...

Smoking is an important risk factor for atherosclerosis. We compared tobacco smoke filtrate with benzo[a]pyrene (a prominent xenobiotic component of tobacco smoke) for the capacity to induce stress proteins and cause cell death in human monocytes and vascular endothelial cells, two cell types that are involved in the formation of atherosclerotic lesions. Exposure to freshly prepared filtrates o...
