It is possible for a risk to be so small that it is not worth considering. It is possible to be hit by a bolt of lightning from a far-off cloud on a sunny day - a 'bolt from the blue'. This risk is not worth considering when you are deciding whether or not to go to the shops.Grandma Death said:Passive smoking risks are well documented and the risk is there however small regardless of ventilation. If for example you used that station concourse twice a day for all of your working life then the risks exist-and what about the people that work on a station concourse-their exposure is even greater. No matter how you look at it-smoking in public is a health risk. We could spend all day churning out risk factors/probablities-but one thing you cant eliminate is the actual risk.
And passive smoking risks are, in fact, surprisingly badly documented. The evidence is far from clear-cut and Richard Doll, no less, the scientist who first documented the link between smoking and lung cancer, was far from convinced. It is very difficult to separate out lifestyle from passive smoking - essentially, if you spend a lot of time around smokers, you're more likely to have a bad diet and not exercise too much than those who avoid smoky atmospheres, which makes definitive studies very difficult.
