Experts debate the products' potential to help smokers quit and the tobacco industry's true intentions. Some argue for collaboration with the industry, while others fear it may be a Trojan horse.
A new study finds that as smoking declines overall, remaining smokers are actually less likely to smoke and more likely to quit. The study challenges the need to promote e-cigarettes as a harm reduction strategy, suggesting that current tobacco control policies have been successful in reducing smoking prevalence.
Researchers at Georgia State University found a doubling of establishments permitting smoking in designated dining areas and outdoor spaces. The percentage of restaurants and bars allowing smoking nearly doubled from 9.1% to 17.6% between 2006 and 2012.

Research published in Tobacco Control found that including experimenters in e-cigarette prevalence studies can lead to inaccurate results. The study suggests setting a threshold of six days out of the past 30 for more accurate monitoring of population health trends. Current smokers were more likely to use e-cigarettes than former or ne...

Researchers suggest four strategies to prevent marijuana use among minors: increasing prices through tax policy, regulating retail availability, preventing accidental ingestion by children, and restricting marketing. These measures can help minimize youth access to marijuana.
Researchers at British American Tobacco developed a new smoking-specific survey, TQoLIT, to assess the impact of next-generation tobacco and nicotine products on 'otherwise healthy' smokers. The tool improves upon existing general health questionnaires by reducing ceiling effects and detecting specific smoking-related health changes.
