Simply speaking while infected can potentially spread COVID-19
COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing; however, speaking while near one another is also risky. In Physics of Fluids, scientists used smoke and laser light to study the flow of expelled breath near and around two people conversing in various relative postures commonly found in the service industry.

Dual smoking and vaping doesn't cut cardiovascular risk: Boston University study
Cardiovascular disease is the leading cause of death associated with smoking cigarettes. But as use of e-cigarettes (''vaping'') becomes more popular, including as a way to cut back on cigarettes, little is known about its effect on cardiovascular health. Now, a new Boston University School of Public Health (BUSPH) study, published in the journal Circulation, finds that vaping may not cut risk of cardiovascular disease in the way that most adults use them--in combination with cigarettes. (2021-01-06)

Vaping combined with smoking is likely as harmful as smoking cigarettes alone
People who smoked traditional cigarettes in addition to using e-cigarettes experienced health effects as harmful as those who smoked cigarettes exclusively; those effects are associated with a higher risk for cardiovascular disease and death. In a large data analysis of more than 7,100 U.S. adults, researchers examined the association of cigarette and e-cigarette use with inflammation and oxidative stress as biomarkers predicting cardiovascular disease. (2021-01-04)

New studies suggest vaping could cloud your thoughts
Both adults and kids who vape were more likely to report difficulty concentrating, remembering, or making decisions than their non-vaping, non-smoking peers on two annual national surveys. Survey results, which were analyzed by a team of URMC researchers, also suggest that kids were more likely to experience mental fog if they started vaping before the age of 14. (2020-12-28)

Light smokers may not escape nicotine addiction, study reveals
Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria.

Vaping may increase respiratory disease risk by more than 40%: BU study
A growing body of evidence points to the health risks of using e-cigarettes (or ''vaping''). But because e-cigarettes are marketed as a less harmful alternative to traditional cigarettes, it has been difficult to tell whether the association between vaping and disease is just a matter of smokers switching to vaping when they start experiencing health issues. (2020-11-12)

Editorial: New research strengthens the case for e-cigarettes as smoking cessation aids
Using FDA-approved smoking cessation aids increases the likelihood of success, but many smokers who use these therapies still struggle to remain tobacco free, says Nancy Rigotti, an investigator at Massachusetts General Hospital. Rigotti sees a promising role for e-cigarettes as a new option to help smokers quit. (2020-11-10)

E-cigarettes can be 'gateway' to cigarettes for teens with no prior intention to smoke
Cigarette smoking remains a leading preventable cause of morbidity and mortality in the United States. And while adolescent cigarette smoking has declined over the past several decades, e-cigarette use presents a new risk for nicotine use disorder. A new study, published Nov. 9 in the journal Pediatrics, finds that e-cigarette use is associated with a higher risk of cigarette smoking among adolescents who had no prior intention of taking up conventional smoking. These findings have strong implications for practice and policy, researchers say. (2020-11-09)

Children exposed to tobacco smoke at home have worse heart function as adults
The more secondhand tobacco smoke children breathe at home while growing up, the higher their chance of developing markers of decreased heart function as adults. Children should be protected from secondhand smoke because of its harmful effects during childhood and the potential long-term negative impacts, whether or not they smoke as adults, researchers said. (2020-11-09)

Coming out as bisexual associated with increased risk of smoking: BU study
For many years, lesbian, gay, bisexual, and other non-heterosexual (LGB+) folks have been known to be more likely to smoke than their straight counterparts. But a new, first-of-its-kind Boston University School of Public Health (BUSPH) study paints a more precise picture by looking at LGB+ identities separately and over time, finding that bisexuality is the identity most associated with smoking, especially around the time of coming out. (2020-11-06)

NYCHA secondhand smoke policy needs more time and effort to show how well it works
One year into a smoking ban in buildings run by the nation's largest public housing authority, tenant exposure to secondhand smoke in hallways, stairwells, and apartments has not declined, a new study shows. Among the explanations for this, investigators say, are delays in promotion and enforcement, including putting up signage and training building managers, and reluctance among nonsmokers to report violations. They also cite lack of smoking cessation services as a possible factor. (2020-11-05)
