Cigarette smoke during pregnancy

Today was the first time that I saw a pregnant woman smoke cigarettes and today was the first time that I felt disgusted and judgy at another pregnant woman. There is seriously no excuse for why you would subject your innocent unborn child to that and this woman and every pregnant woman who smokes should be ashamed. Please do not smoke during pregnancy, I've seen first hand what it can do to a full grown adult let alone a baby who's body is just developing!! I'm so mad I could just go over ther and throw her whole box away. I'm sorry if this offends anyone but it's totally unacceptable...
