In Europe (yesIknowwe'repartofEuropebutIdon'tcare) I think it's still more popular than in the UK - Amsterdam and France, for example.
A lot of people smoke originally because of social pressure and then because of habit / stress.
I hear there's also an advertising campaign planned for the cigarettes showing the lungs of a smoker compared to a healthy person.
...Imagine if they tried banning chocolate?
