Smoking Ban

I find it a bit ridiculous that smoking is being banned on parks and beaches now. What is the purpose of that? Smoking is a personal choice and people who smoke should have the freedom to exercise that choice. It is understandable to ban smoking in buildings, but banning it outdoors is not fair. There is virtually no risk of secondhand smoke outside. Places with smoking bins outside allow for cigarette butts to be disposed of properly. I feel this ban on outdoor smoking a bit too far.
