title: Acute effects of nicotine on alcohol cue-reactivity in nondependent and dependent smokers.
abstract: Evidence from alcohol self-administration studies suggests that nicotine replacement therapy may influence subjective and behavioral responses to alcohol. However, its effect on alcohol cue-reactivity is unknown. The present study examined the impact of acutely administered nicotine on subjective responses to alcohol-focused pictorial stimuli. In a mixed within/between-subjects design, nondependent smokers (n = 51) and dependent smokers (n = 45) who socially drink were assigned to either a nicotine (4 mg) or placebo lozenge condition following overnight tobacco abstinence. Following lozenge absorption, participants viewed neutral images followed by alcohol-focused pictures. Craving measures for alcohol and tobacco were completed at baseline, following lozenge absorption, following neutral cues, and following alcohol cues. The presentation of alcohol cues increased alcohol-related craving relative to neutral cues, especially among men, but the administration of nicotine did not influence the magnitude of these effects. Nicotine lozenges were found to decrease intentions to smoke and withdrawal-related craving in dependent but not in nondependent smokers. Finally, the presentation of alcohol cues was found to increase intentions to smoke relative to neutral cues across participants regardless of lozenge condition. Findings suggest that although the presentation of alcohol cues can increase alcohol- and tobacco-related cravings in smokers, such effects do not appear to be affected by acute nicotine administration.
