Let's ban airplanes and cars too... They emit harmful gases.
People just need to be considerate... Whether they're a smoker, drinker, dipper, seed spitter, eat snacks, fart, talk... On a golf course.
No need to ban any of it... Just be considerate and ask others around you to be considerate.
I smoke cigars on occasion while golfing, and it's normally not an issue because I walk the majority of the time, and I'm considerate of others. On the rare occasion I get paired up in a cart with someone, on a day a brought a cigar, I let them know I brought a cigar and I can get a separate cart if it will bother them.
No one is going to get cancer from getting an occasional whiff of a cigar on a golf course... That is the dumbest thing I've ever heard. Educate yourself. And yes, I've had family members die from cancer as well (both lung cancer, and both were big time smokers)... But that doesn't mean everyone is going to die from catching a whiff here and there.
From a business perspective... A ban would be a terrible business decision. Let's just ban everything that annoys anybody... And not have golf anymore
Yes, some would have planes, cars, electricity... etc., banned if they could. 2/10 is an opinion, 5/10 is a debate, 7/10 is a bill, 8+/10 is a law. Bottom line, enough people annoyed/offended/dead, facts or no facts, the matter is ban fodder. BTW, personally I would never vote (if I had one) against cigars altogether. Just in closed spaces.
