As a non-smoker I’ve come to prefer the sight of someone smoking over the sight of someone vaping.

The smaller units with the clear reservoir where you can see the nicotine fluid are especially disgusting to watch someone suck on. When someone smokes a cigarette at least you might be reminded of some of the great, classy smokers like Bacall, Bogart, Dean, Lake, etc. Not so with vaping, no one has made that look sexy yet. Also, most smokers these days have the tact to smoke inconspicuously but vapers have no issue vaping right in your face.
