I'm not claiming damaging effects. For the record, I've never asked a smoker not to smoke, other than when in a designated non-smoking area.podgerodge said:I will go on believing that the potential damaging effects of a whiff of smoke in the outside air are negligible compared to the rest of contaminants in the city.
But I do believe that it would be simple good manners to
a) not litter butts
b) not smoke in areas where your smoke will be difficult for others to avoid (e.g. queues, crowded platforms etc).
