E-cigarettes could save lives: study

(News.com.au)

E-cigarettes could lead to a 21 per cent drop in deaths from smoking-related diseases in those born after 1997, according to a study published in Nicotine & Tobacco Research.

The US study, funded by the National Institute on Drug Abuse, the National Cancer Institute and the Cancer Intervention and Surveillance Modeling Network, found that under most plausible scenarios e-cigarettes and other vapour products have a generally positive public health impact.

Many studies have sought to assess the impact of e-cigarettes on public health, with conflicting results. This year a University of California study of high school students found that those who used e-cigarettes were more than twice as likely to also smoke traditional cigarettes.

The latest study differed from earlier ones because it summarises patterns of use from national data, the authors said.

Previous studies have used local data that may have unusual patterns and are not necessarily representative of the whole country.

The latest study distinguishes between youths who vape who would not otherwise have taken up any nicotine product, and those who vape, who would otherwise have smoked cigarettes. When both those populations were taken into account, the benefit outweighed the harm, the study found.

Many experts believe there are health benefits for smokers who switch completely to e-cigarettes.

“While the data are still not as clear as we would like, we present the entire picture with national data so we think our estimates are as good as we can get,” said David Abrams, executive director of the Schroeder Institute of Tobacco Research and Policy Studies at the Truth Initiative.

Most previous studies count as e-cigarette users anyone who has vaped within the past 30 days. That can include someone who goes to a party and vapes once or twice.

“Those are not the people we are concerned with,” David Levy, a professor of oncology at Georgetown Lombardi Comprehensive Cancer Center and the study’s lead author said in an interview. “We tried to get an idea of the number of people who progressed to established use.”

On May 5 the FDA announced a final rule extending its tobacco authority to include e-cigarettes, pipe tobacco, cigars and hookah. The rule, which becomes effective in early August, requires companies to seek marketing authorisation for any tobacco product introduced after February 15, 2007.

Levy and other e-cigarette advocates say excessive FDA regulation could stifle the development of safer products that could more effectively displace cigarettes.
