Yup, dcm, when you don't like the facts (15%) then just say they're wrong. 
I don't know the age group of 'everyone you know' but I'd best they ain't teenagers.
And I'd bet most of them make the simple trip to get their cigs at the store. Just as they go to the liquor store instead of making their own cheaper booze. And I bet there are less of them doing that this year than 2 years ago.
See? I can do the 'I bet' thing, too. But I bet my bets are based deeper in facts than yours :)
