NewsBreak: Tobacco Stocks Mixed as Research Links E-Cigarettes to Cancer in Mice

Tobacco stocks were mixed amid new findings showing that exposure to nicotine in e-cigarette vapor had caused cancer in mice, and was likely “very harmful” to humans, according to New York University.

• The study is the first to link vaping nicotine to cancer.

• The amount of smoke the mice were exposed to was similar to what a human would inhale if they vaped regularly for about three to six years, estimated Moon-shong Tang, a professor at the NYU School of Medicine.
