Videos depicting the risks and solutions were most effective, especially when including recommendations for cessation and exposure reduction.
New research by British American Tobacco indicates that modern oral nicotine products (MOPs) are less biologically active than traditional cigarettes and snus, with some products failing to elicit a biological response. The study suggests MOPs may be a reduced-risk option for users who switch completely from smoking.
A new study found that wildfire smoke leads to a 6.1% increase in medical visits for asthma patients compared to days with similar pollution levels from other sources. The research team suggests that wildfire PM is more hazardous than non-wildfire PM for asthma patients, likely due to differences in chemical composition or human behavior.
Researchers detected nitrous acid levels two to four times higher than expected in wildfire plumes globally, driving increased ozone pollution and air quality harm. The chemical accelerates the formation of lung-damaging ozone pollution downwind of fires, with significant variations depending on ecosystem type.
A New Zealand survey found that e-cigarette use is increasing among smokers and recent quitters, with most common reasons being to help quit or cut down on smoking. The study suggests e-cigarettes are contributing to reducing smoking prevalence, but more work is needed to achieve the goal of becoming smokefree by 2025.
