[A]n adolescent who had smoked just one cigarette at age 11 was twice as likely to be a regular smoker at age 14 than those who had not tried a cigarette at age 11. This was true even for the kids who did not smoke again in the intervening years.

How can the 14 year old be considered a 'regular smoker' when he hasn't smoked in three years?

I assume those were years in which he was 11, 12, and 13?

An implied floor(age) hadn't occured to me. I suppose that means that on average the 14 year olds in question would have 0.5 years in which to become a regular smoker. An... interesting... thing to measure. The ones that would be most likely to be smokers would then be those that are closer to 15 than 14.
