I have a neighbor that has two small children and they are serious chain smokers. I've always thought that smoking around children is a form of child abuse. But I've never wanted to say anything to them because despite my personal feelings, smoking around kids is discouraged but not illegal (yet). At least not where I live. So all I do is walk by and do nothing about it. Now, I am a nursing student. And as a future nurse, I feel obligated to do something. But what can I possibly do considering it is not illegal? If I talk to them, they could retaliate in some way. I don't really know them so I don't have a clue how they would react. I am just fearful for the kids (ages 2 and 4). Should I just mind my own business? I'm not trying to be a nosey neighbor. I just don't want to see the kids develop asthma or cancer or something.
