“…First, identifying and reaching teen smokers is difficult: Prior teen smoking cessation studies have been conducted primarily in self-selected or convenience samples of small size Sussman 2002), limiting the trials' generalizability. Second, past adolescent cessation studies have mostly focused on daily smokers, with little attention paid to infrequent smokers : In a recent meta-analysis of 48 adolescent cessation trials, the level of baseline smoking averaged 10.44 cigarettes per day (Sussman, 2006), reflecting the prevalent research interest in daily smokers. Because infrequent smokers constitute a sizable portion of adolescent smokers (Centers for Disease Control and Prevention, 2006;Johnston et al, 2006;Mowery et al, 2004), are at high risk of smoking escalation and adult smoking (Bricker et al, 2006;Centers for Disease Control and Prevention, 1998;Choi et al, 1997;Chassin et al, 1990), and have difficulties quitting smoking (CDC, 1994), expanding research to include infrequent smokers is an important next step.…”
