Like many, I have never smoked but grew up in a house with a parent who smoked. The smell has never really bothered me. In fact, on my last cruise I spent some time in the enclosed "smokers" casino room, to play a slot machine that was only there. Most of the time, nobody was smoking in there. There was one guy who came in occasionally to smoke but not gamble (yes, that's against the rules, but since I was gambling without smoking we had an offset 🤣). I'm not a believer in the hazards of occasional secondhand smoke. I'm sure it is more dangerous than bubbles on my balcony, but we're splitting hairs.
