There is a good stop smoking add here. It's for Nicorette, which is a gum that theoretically helps you stop smoking.
There is a woman at her desk working. The nicotine goblin says to her: aren't you going out to join your friends outside for a nice smoke? She looks outside to see that there is hurricane force winds, & everyone is holding on to whatever they can, getting soaked, shivering, trying to smoke. She replies: No, don't think I'll miss that! And then puts the gum in her mouth.
The funny part about that is, you see the same seen everytime there is crap weather out. All you have to do is look near the entrance to any office building.

Ottawa is totally non-smoking throughout the city (in all public places).
