In some outdoor environments, like football grounds and railway stations, there is genuine cause for concern. But in other places, there are pretty obvious facts about air circulation which mean the potential for harm is far less. Certainly, stopping people smoking in their homes is taking things a bit far.

You've got to get this issue down to what's reasonable and sensible. That's an extreme, fundamentalist position. And I don't think we're that kind of country, are we?
