I fully support smokers being very courteous and ever thoughtful of others. But I think there has to be a line. As I said, there are heaps of things I could list that neighbours do that can be damaging to health. No one suggests outlawing alcohol though, given the research on it's damaging effects to just to the person drinking but others around them. Could you imagine the outcry? Why? bc drinking is more socially acceptable now than smoking.
