The study authors are calling for regulations prohibiting brands from making claims that e-cigarettes can help people stop smoking, at least until there is scientific evidence.
The tobacco vapor electronic cigarette association criticizes the study for its limited data and says the e-cigarettes are vastly less harmful than tobacco.
Researchers acknowledged just 88 of the people who participated in the study used e-cigarettes.
Because e-cigarettes are unregulated, consumers don't know what their putting into their bodies, and there have not been any long studies on the health effects.
