Effects of d-amphetamine and smoking abstinence on cue-induced cigarette craving.

In this study, the authors investigated the effects of the indirect dopamine agonist d-amphetamine (AMPH) on cue-induced cigarette craving in smokers. Abstinent or nonabstinent cigarette smokers (N=21) rated their cravings for cigarettes and for food (control) after pretreatment with AMPH (15 mg) or placebo and before and after viewing blocks of smoking-related, food-related, and neutral pictures. Before the cues were presented, AMPH increased cigarette craving and decreased food craving. Smoking and food cues increased craving for cigarettes and for food, respectively. AMPH also further increased cigarette craving (and decreased food craving) after cue presentation, but it did so regardless of cue type (food or smoking). Smoking abstinence markedly increased craving regardless of cue presentation or drug condition. These results suggest that both AMPH and smoking abstinence can increase cigarette craving, but they do not appear to specifically affect responses to conditioned smoking-related cues.
