I vape in the open parks and such. imho any smoking ban in those areas are due to .... litter and fire hazards which do not exist with vaping. I smoked in those areas as well since I always carried out my butts and was very aware of not making a fire hazard. Many smokers just throw their butts anywhere starting fires beside roadways and such. 2 legged dumb butts are everywhere.
I always tried to be a courteous smoker as I do with my vaping.
IMO, you are mistaken about why smoking is banned in outdoor locations. I believe it is partly due to reasons you stated as mostly due to the smell factor that a non-smoker can encounter when walking, playing, standing in a park like setting where smoking is allowed. And as the argument works for indoor places, it can / does work for outdoor places.
I play disc golf often and last week was ahead of a group that were vaping. I too was vaping. There were several times when I was more than 150 feet from this group and the air 'all around me' smelled like cotton candy. I like that smell. It was very nice during this rare 80 degree day in early May. Made me feel like being in a park as a kid. Took me a moment or two to realize it was coming from the group behind me, and so when they caught up to me (for around the 10th time that day), I asked what flavor one was vaping and he said "pineapple custard." Not sure how one (me) gets cotton candy from that, but I told him it smelled very good.
To me.
But to another, that could be downright disgusting and offensive that someone dare 'pollute' the fresh park air with that odor.
With vaping, or smoking, outdoors the odd thing is that you have zero control how the wind will handle your exhale. Thus a case could be made, rather easily, that if vaping odors are offensive, then it is worse to do it outside as compared to inside, because of the wind factor.
So, this notion of don't vape where you can't (or wouldn't) smoke, and combined with 'common courtesy' has to absolutely apply to outdoor public places, or someone is being disingenuous. More likely, if you are okay with vaping outdoors in public, and harsh on people who vape indoors in public, then chances are you're just being hypocritical. Or perhaps, you simply think wind factor is a non issue and that if a non-smoking/non-vaping person gets a whiff of your (disgusting) scent, and dislikes the practice, that is on them entirely and not on you, for you had no intention of having that 'cloud' end up in their nostrils. But it did.
Furthermore, if you vape indoors in own space, but ever do so with windows down or outdoors on own property, and wind is at all a factor, then you done just went and violated 'common courtesy' and so, we are plausibly at a place where there are zero locations on planet earth where it is 100% okay to vape/smoke, without someone possibly having a 'cloud' end up in their face.
Won't anyone think of the childish adults?
