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.

Social interactions after isolation may counteract cravings
Social interaction may help reverse food and cigarette cravings triggered by being in social isolation, a UNSW study in rats has found. The study, published in Scientific Reports, used an animal model of drug addiction to show that a return to social interaction gives the same result as living in a rich, stimulating environment in reducing cravings for both sugar and nicotine rewards.

Ancient indigenous New Mexican community knew how to sustainably coexist with wildfire
Wildfires are the enemy when they threaten homes in California and elsewhere. But a new study led by SMU suggests that people living in fire-prone places can learn to manage fire as an ally to prevent dangerous blazes, just like people who lived nearly 1,000 years ago. (2021-01-27)

Adults with cognitive disabilities more than twice as likely to use e-cigarettes
In the first national study to assess use of e-cigarettes among adults with disabilities, George Mason University's College of Health and Human Services researchers found that e-cigarette use was more than twice as likely among adults with a cognitive disability (12.0%), an independent living disability (11.0%), or two or more disabilities (9.2%), compared to adults without disabilities (4.8%).

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. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment. (2020-12-23)

E-cigarettes, as consumer products, do not help people quit smoking, study finds
E-cigarette use has risen steeply and mostly without regulation over the past decade. The devices have diversified into a dizzying array of vape pens, tank systems, ''mods,'' and more, mass-marketed and sold to the public. The U.S. Food and Drug Administration (FDA) is in the midst of considering whether to approve thousands of pre-market applications for the sale of e-cigarettes as consumer products. (2020-12-22)

Wildfire smoke carry microbes that can cause infectious diseases
Wildfire smoke contains microbes, infectious agents that might cause diseases. In a perspective piece published in Science, researchers at UC Davis Health and the University of Idaho proposed a multidisciplinary approach to study the health impacts of microbes carried by wildfire smokes. (2020-12-17)

Vaping could nearly triple the chance of smoking in teens
A new study offers strong evidence that kids who use e-cigarettes are more likely to take up smoking or smokeless tobacco, researchers say. Teen boys who vaped were almost three times as likely to start smoking as other teen boys with similar risk profiles and more than two times as likely to try smokeless tobacco, the study from The Ohio State University found. (2020-12-16)

Healthy muscles are a carrot on a string for healthy lungs
Scientists show effectiveness of carrot-based Japanese herbal medicine called ''Ninjin'yoeito'' in improving muscle atrophy in the hind legs of mice exposed to cigarette smoke through an increased expression of PGC-1α, positioning the medicine as a potential treatment for sarcopenia frailty-related complications with chronic obstructive pulmonary disease (COPD). Their findings were published online in the international scientific journal ''International Journal of Chronic Obstructive Pulmonary Disease'' on November 27, 2020. (2020-12-02)

Ozone breaks down THC deposited on surfaces from thirdhand cannabis smoke
Second- and thirdhand tobacco smoke have received lots of attention, but much less is known about the compounds deposited on surfaces from cannabis smoke. Now, researchers reporting in ACS' Environmental Science & Technology have discovered that ozone --a component of outdoor and indoor air -- can react with tetrahydrocannabinol (THC), the psychoactive component of cannabis, on glass or cotton surfaces to produce new compounds, which they characterized for the first time. (2020-12-02)

Smoking, tobacco use among teens continues to drop even as use of e-cigs grows

(2020-11-25)

Breathing problems in teens: COVID-19 or lung injury due to vaping?
In a case series of three teen patients, UC Davis Health pediatricians present common manifestations of COVID-19 and lung injury due to vaping (EVALI). As EVALI and COVID-19 share many symptoms, it is critical for health providers to get the vaping history of teenagers with unexplained breathing problems. (2020-11-19)

Pod e-cigarettes less harmful than regular cigarettes, new study finds
In the first-ever clinical trial of fourth-generation electronic cigarettes, researchers found that adults who switched to e-cigarettes had lower levels of a major carcinogen compared to smokers who continued using combustible cigarettes. (2020-11-18)
