A Boston University School of Public Health (BUSPH) researcher has concluded that electronic cigarettes are much safer than are traditional cigarettes and show promise in the fight against tobacco-related diseases and death, according to physorg.com story provided by the Boston University Medical Center.

The report bucks the concerns raised by the Food and Drug Administration.

The review, which will be published online ahead of the print version in this month's Journal of Public Health Policy, is the first to examine comprehensively scientific evidence about the safety and effectiveness of electronic cigarettes, said Michael Siegel, professor of community health sciences at BUSPH.

"Although the existing research does not warrant a conclusion that electronic cigarettes are safe in absolute terms and further clinical studies are needed to comprehensively assess the safety of electronic cigarettes, a preponderance of the available evidence shows them to be much safer than tobacco cigarettes and comparable in toxicity to conventional nicotine replacement products."
