A University of Louisville professor who is the lead author of the American Heart Association’s policy statement on e-cigarettes has raised the same type of concerns expressed in a recent New England Journal of Medicine showing that e-cigarette vapor can contain cancer-causing formaldehyde at levels up to 15 times higher than regular cigarettes.

Dr. Aruni Bhatnagar, the Smith and Lucile Gibson Chair in Medicine at the University of Louisville, chaired a 10-member American Heart Association panel of experts in formulating the association's first-ever policy statement on e-cigarettes released in August 2014. The article's findings echo the concerns raised by Bhatnagar and the group over what is still unknown about e-cigarettes.

Bhatnagar's voices his concerns in the video shown here.

"People need to know that e-cigarettes are unregulated and there are many variables that we don’t know about them," Bhatnagar says. "Recent studies raise concerns that e-cigarettes may be a gateway to traditional tobacco products for the nation’s youth, and could re-normalize smoking in our society.”

Because e-cigarettes contain nicotine, they are tobacco products and should be subject to all laws that apply to these products, according to recommendations in the policy statement. The association also calls for strong new regulations to prevent access, sales and marketing of e-cigarettes to youth, and for more research into the product’s health impact.
