Vaping is not necessarily a healthier option (does not discount from the fact that cigarettes and other tobacco products are unhealthy). A swathe of severe lung illness (including several fatalities) have been identified as caused by vaping. Based on current reports (and not a research/study), vaping deaths appear to have a shorter time-span than tobacco. It is also estimated that pure nicotine delivery service might be more addictive (due to higher concentration of the dosage) than cigarettes.
I'm not saying that tobacco should not be banned or controlled even more, but vaping is NOT a healthier alternative.
