Reactivity to in vivo smoking cues in older adolescent cigarette smokers

Most smokers initiate smoking in adolescence, and craving for cigarettes may play an important role in maintenance of smoking behavior and relapse to smoking during a quit attempt. Although a significant body of literature explores cue-reactivity in adult smokers, little has been published on cue-reactivity among adolescent smokers. In a previously published work, we found that videotaped smoking cues may not be robust in eliciting craving among adolescent smokers. Hence, in this preliminary study, we examined reactivity to in vivo smoking cues among adolescent smokers (N=11, average age=18.1 years, range=15-19 years, predominantly female). Participants were presented with in vivo smoking and neutral cues (counterbalanced). We recorded subjective craving and real-time heart rate in response to each type of cue. Adolescent smokers had a significantly greater "desire'' to smoke (p <. 05) in response to smoking cues vs. both baseline and neutral cues. Participants had faster heart rates after the smoking cues during the epochs of 21-30 s and 31-40 s (p values <. 05) as compared with baseline, and mean heart rate was higher during the smoking cues relative to neutral cues among participants who received the smoking cues first (p <. 05). Results of this preliminary study further demonstrate the feasibility of conducting cue-reactivity studies with adolescent cigarette smokers. Findings from this study suggest that adolescent smokers may show patterns of responding to smoking cues similar to those of adult smokers. Implications for future laboratory studies with adolescent smokers are discussed.
