As a non-smoking son of a heavy smoker (now deceased because of it) I can offer the following comments.
I absolutely detest, to the point where it makes me gag, the smell, nay reek, of cigarette smoke. Smokers think once they exit the smoking room it's all gone. It's not. It sticks in their clothes and their breath is foul with it. I've had to leave rooms because of it... I can even smell it in a car ahead of me. It's foul. Should be a complete ban on smoking in public places, and yes, roads are public places.
Now, vapping. No problem at all. In fact, some of the mixes actually smell quite pleasant.
So, the take-out from my comment. Smokers, you may not be able to smell it, by trust me, non-smokers can. And it's extremely unpleasant. Please, have some consideration. I don't urinate in your coffee, please don't pollute up my air. Yes, when I can, I move away, but sometimes, like at my work desk, I don't have that option.
