How is the air quality in Havana? Especially in old Havana? Have read a lot of mixed reviews with some claiming that they were hardly bothered with cigarette or cigar smoke and some saying that Cuba is not for those sensitive to smoke.
I really want to visit Cuba but am afraid that I'll suffer from anxiety which happens when I feel suffocated. Is it worse that Chinese cities (which to me is pretty bad)? I don't get bothered in places like Seoul where everybody smokes but they do it away from common areas.
Am also quite concerned about the exhaust smoke from old vehicles as I understand old Havana is best explored on foot and wouldn't want to be inhaling all that black smoke.
