| * Additional information on smoking_habit_adu_c_2 with four categories: never-smoker, current smoker, ex-smoker, and recent starter. A person that smokes or has smoked for less than a year, is not seen as a smoker. Thus, a person that has smoked for a few months and then stopped is categorized as a 'never-smoker'. A person that recently started smoking and is currently still smoking is still seen as a never smoker because that person currently smokes for less then a year. However, these persons are categorized as a 'recent starter'. | * Please note that in contrast to the previous calculation, cigars are now regarded to as 1 cigarette (and not as 3)\\ |
