Switching to e-cigarettes is not an effective way to get people to quit smoking.
That's according to a new study from the University of California San Francisco.
E-cigarettes are sometimes marketed as a healthier alternative to smoking tobacco. But researchers looked at the exposure from secondhand vapors and found negative impacts on lung function. They also found using e-cigarettes is linked to lower odds of quitting traditional cigarettes.
The study's authors say e-cigarettes should be prohibited wherever tobacco cigarettes are not allowed.
