MR R Feal-Martinez, in answer to your letter we non-smokers are not complaining just on the issue of proving passive smoking is harmful.

Have you lost the plot?

We non-smokers don't have to prove anything, we choose to be non-smokers for lots of reasons, and most of us don't like our personal space invaded by fumes and you are saying that as it's only an irritant we should just be quiet and shut up.

I don't think so. Perhaps we are fed up with people puffing smoke at us going to the pub, and returning home to find we are stinking of tobacco smoke, and have to wash all of our outer coats as well as all our other garments.

Perhaps we are fed up with having a meal and, while eating, being subjected to the terrible smell of tobacco smoke wafting over from the smoking area.

Next to chewing gum, look to the floor, it's littered with cigarette ends, which people have to be paid to clean up.

And last but not least, what is printed on each packet of cigarettes...? "cigarettes can kill."

So someone else as well as me shares my view, or they wouldn't put it on every packet of cigarettes would they?

Whether they can kill or not we will differ on, but I for one would not dream of "puffing away" while offending so many other people.
