A new measure of youth cigarette smoking.

ABSTRACT: American students' 30-day smoking prevalence has decreased dramatically over the past two decades. The frequency of smoking within the 30-day measure has shifted from heavy smoking (>1/2 pack/day) toward light smoking (<1 to 5 cigarettes/day). 30-day prevalence thus understates the extent of the decline in youth smoking. To capture this shift toward less frequent smoking among the decreasing proportion of students who smoke, I develop a new index: the average number of cigarettes smoked per student per day (ACSD), using data from Monitoring the Future. To calculate ACSD I assign a specific number of cigarettes to each of 7 response options to the question, "How frequently have you smoked cigarettes during the past 30 days?" Response options range from "not at all" (assigned 0 cigarettes) t
