Lowering nicotine loosens tobacco’s hold

A team of researchers, including two at Brown University, show that when people smoked cigarettes with less nicotine, they smoked less, felt less craving, and tried to quit more. Results appear in The New England Journal of Medicine.

PROVIDENCE, R.I. [Brown University] — Two Brown University researchers are co-authors of a new study published in the New England Journal of Medicine showing that nicotine content is a significant determinant of cigarette use and dependence. (more…)

Lesbian and gay young people twice as likely to smoke and drink alcohol

Young people who identify as lesbian, gay or bisexual are twice as likely to have smoked than their heterosexual peers, according to new research published in BMJ Open. Lesbian and gay young people were also more likely to drink alcohol frequently and more hazardously.

The interdisciplinary research team comprised researchers from five UK Universities (UCL, University of Cambridge, London Metropolitan University, De Montfort University Leicester and Brunel University), a doctor working in General Practice and a consultant from Public Health England. (more…)

Teens Who Smoke and Drink May be More Likely to Abuse Prescription Opioids Later

Adolescents who smoke cigarettes or use alcohol or marijuana may be at greater risk for subsequent abuse of prescription opioids as young adults, according to a new study by Yale School of Medicine.

The researchers believe their findings are the first to demonstrate that early alcohol, cigarette, and marijuana use are all associated, to varying degrees, with a two- to-three times greater likelihood of subsequent abuse of prescription opioids. The study appears online in the Journal of Adolescent Health. (more…)

Curbing Tobacco Use by Growing Less

UCLA researcher initiates successful crop substitution project in tobacco-rich China

In China, 350 million people smoke. Each year, 1 million die from smoking. Many more become disabled. Approximately 20 million Chinese farmers produce the world’s largest share of tobacco, nearly 40 percent of the global supply.

What is the key to cutting the number of deaths and smoking-related health problems? Convince Chinese farmers to grow some other crop.

Virginia Li, a professor of community health sciences at the UCLA Fielding School of Public Health, set out to do just that. She contacted local Chinese agriculture officials in Yunnan Province, where Asia’s largest cigarette manufacturer is located. Li and her local partners designed a tobacco crop–substitution project, the core of which is a farmer-led, for-profit enterprise. (more…)

UF Study Shows Tundra Fires Could Accelerate Climate Warming

GAINESVILLE, Fla. — After a 10,000-year absence, wildfires have returned to the Arctic tundra, and a University of Florida study shows that their impact could extend far beyond the areas blackened by flames.

In a study published in the July 28 issue of the journal Nature, UF ecologist Michelle Mack and a team of scientists including fellow UF ecologist Ted Schuur quantified the amount of soil-bound carbon released into the atmosphere in the 2007 Anaktuvuk River fire, which covered more than 400 square miles on the North Slope of Alaska’s Brooks Range. The 2.1 million metric tons of carbon released in the fire — roughly twice the amount of greenhouse gases put out by the city of Miami in a year — is significant enough to suggest that Arctic fires could impact the global climate, said Mack, an associate professor of ecosystem ecology in UF’s department of biology.

Working More Than 11 Hours Increases Chances For Heart Attack By 2/3

Those who spend more than 11 hours at work increase their chance of having a heart attack by two thirds, according to a new study.

Researchers from University College London say the risk is so great that GPs should ask patients what hours they work along with how much they drink or smoke. (more…)

Fireworks Produce High Levels of Toxic Particles

Fireworks can be spectacular. However, the gas and smoke produced by the colorful explosions carry extremely high levels of toxic particles, according to a study by Audrey Smargiassi, a professor at the Université de Montreal Department of Environmental and Occupational Health.

Smargiassi conducted one of the first studies examining the composition of the emitted gases and the concentration of the particles. In addition, her study is unique as she collected her data below the fireworks display where spectators usually stand. Previous studies usually collected data from nearby rooftops.

The study was conducted in 2007 during nine separate shows presented at La Ronde amusement park where 5.7 million spectators attend an international fireworks competition every summer. (more…)

Berkeley Study Shows Ozone and Nicotine a Bad Combination for Asthma

Another reason for including asthma on the list of potential health risks posed by secondhand tobacco smoke, especially for non-smokers, has been uncovered. Furthermore, the practice of using ozone to remove the smell of tobacco smoke from indoor environments, including hotel rooms and the interiors of vehicles, is probably a bad idea.
