Carcinogens in cigarette smoke hang around indoors like a bad
smell - we know that. What we didn\'t realise until now is that
nicotine residues absorbed on indoor surfaces (carpets, wallpaper
etc) react with gases in the air to produce even more
cancer-causing carcinogens.

So to the question \'can we implement smoking bans at home?\' I\'m
afraid my answer is no.

Instead we must continue to work at reducing the human impact of
smoking through educating people, raising awareness, offering
support mechanisms to those who\'d like to quit smoking and
finding novel ways to discourage those who are thinking of taking
it up. Slowly but surely we must succeed in eradicating a problem
that continues to plague the developed world and will certainly
become a serious concern in the developing world in the coming
decades.
