I never smoked indoors. Even back before people started getting bent out of shape about second hand smoke, I never smoked indoors. I vape indoors. I vape in my house - and when I'm doing desk work at my jobs, I vape at my desk. My employer encourages my vaping.
I also vape in other places I never would have smoked. Stock yards, barns, and grain elevators are good examples of places I go where smoking is dangerous. Dry manure is flammable and dust in a grain bin is explosive. I stomped out a cigarette in a corral one time when I was young - An hour later there was an ash ring 14 inches deep and 40 feet across. I lit the packed manure like a fireworks punk. If there had been any wind that day, it could have been a serious situation that a garden hose couldn't have handled. --- I vape in all of those sorts of places with no concerns.
