In my English class we were asked should cigarettes be banned, i said yes.What would be a good introduction.?

In my English.Language.Arts class we were asked to pick a controversial topic to persuade. I picked should cigarettes be banned and I said yes. I have my reasons why I said yes but I can't think of a good introduction to start it off. In the intro. I need an Attention Getter which is basically what grabs the readers attention. Background knowledge. And my position statement which would be if I am for or against having cigarettes banned. I am for having cigarettes banned. I need a real good attention getter which is the main part for my introduction.
