Smoking Health & The Public Health

As more smokers pay attention to their lung and their family,especially the kids..the truth of tobacco is more known to the public..and within recent years,there comes the electronic cigarette,as a better alternative to smoking cessation..Recently I read a study that shows e-cigarette doesn't create secondhand harm to people around.If so,the e-cig ban makes no sense.That's a big revolution over secondhand smoke!
