Over the last decade, e-cigarettes have become a $1.5 billion industry. Yet the research on their safety has been scant. The benefits and risks of e-cigarettes are currently being studied, but their popularity has far outpaced the science.
“We should focus on evidence, not theories,” said Dr. Stanton Glantz, a professor in the department of medicine and director of the Center for Tobacco Control Research and Education at UC San Francisco.
A major hurdle in studying e-cigarettes is the fact that there is no standardization across manufacturers; one product is vastly different from the next. However, Glantz said that research does show that they are not harm-free.
Here we compare the ingredients in traditional cigarettes versus e-cigarettes and outline some of the health research.
