I disagree. In most of the US the air pollution is less likely to harm you than vaping would. Sugar is a different story but it's one where you can have a healthy relationship to it, whereas you can't with vaping.
Area wise? Sure.
In regards to population centers?
Air pollution has a known, life long, negative impact. https://nypost.com/2015/05/26/new-yorks-pollution-and-povert...
We don't know what the affects of vaping are, so how can you say that?
Could you elaborate? Why can't one have as healthy a relationship with vaping as with sugar? Are we talking about occasional moderate use, or is it something else?
