Smoking affects the heart, lungs … and bones

Although most smokers realize the habit isn’t good for their hearts and lungs, Washington University orthopaedic surgeon Jeffrey Johnson and other surgeons remind patients that if they need surgery, smoking increases infection rates, makes problems with wound healing more likely and also interferes with bone healing.

Tobacco laws for youth may reduce adult smoking

States that want to reduce rates of adult smoking may consider implementing stringent tobacco restrictions on teens. Washington University researchers discovered that states with more restrictive limits on teens purchasing tobacco also have lower adult smoking rates, especially among women.

Depression in kids linked to cardiac risks in teens

Teens who were depressed as children are far more likely than their peers to be obese, smoke cigarettes and lead sedentary lives, even if they no longer suffer from depression. The research, by scientists at the School of Medicine and the University of Pittsburgh, suggests that depression, even in children, can increase the risk of heart problems later in life.

Genes predict if medication can help you quit smoking

A new study shows the same gene variations that make it difficult to stop smoking also increase the likelihood that heavy smokers will respond to nicotine-replacement therapy and drugs that thwart cravings. The finding suggests it may one day be possible to predict which patients are most likely to benefit from drug treatments for nicotine addiction.

Study looks at discrimination’s impact on smoking

Smoking, the leading preventable cause of mortality in the United States, continues to disproportionately impact lower income members of racial and ethnic minority groups. In a new study published in the American Journal of Public Health, Jason Q. Purnell, PhD, assistant professor at the Brown School at Washington University in St. Louis, looked at how perceived discrimination influences smoking rates among these groups. “We found that regardless of race or ethnicity, the odds of current smoking were higher among individuals who perceived that they were treated differently because of their race, though racial and ethnic minority groups were more likely to report discrimination,” he says. 

New book examines impact of U.S. tobacco industry

WUSTL anthropologist Peter Benson’s new book, Tobacco Capitalism, examines the impact of the transformation of the U.S. tobacco industry on farmers, workers and the American public. The book reveals public health threats, the impact of off-shoring, and the immigration issues related to tobacco production, specifically in the rural, traditional tobacco-growing areas of North Carolina. “There are whole groups of people — farmers and farm workers — in our society who dedicate themselves to growing a crop that is vilified,” Benson says.

Easing FDA tobacco advertising rules around schools could cripple law, new study finds

The FDA, through the new Family Smoking Prevention and Tobacco Control Act, is considering banning outdoor tobacco product advertising at various distances from schools and playgrounds. The tobacco industry is challenging these rules on First Amendment grounds, arguing that they would lead to a near complete ban on tobacco advertising in dense urban areas. A new study by the Center for Tobacco Policy Research (CTPR) at Washington University in St. Louis found that a 1000-foot buffer would still allow for tobacco ads. Smaller buffer zones of 350 feet may result in almost no reduction of outdoor tobacco advertising.

Genes influence how much people smoke and who gets lung cancer

Your DNA influences how much you smoke and whether you will develop lung cancer or chronic obstructive pulmonary disease. A study, led by researchers at Washington University School of Medicine, is the first large-scale effort to match genetics with smoking, lung cancer and COPD combined. The investigators studied 38,000 smokers and found that two groups of gene variants on chromosome 15 influence the risk for all three problems.
