Because I think its important to note that cigarettes kill more then alcohol, car wrecks, and gun related deaths combined every year! If you actually read into the scientific studies and find out how they were conducted you will find only the anti vaping science is rigged for favorable outcomes. And the fall back argument being used saying ?well we just don?t know? only means lets find out! If were going to allow people to continue to smoke then why would we ban vaping?
