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.
在本研究中,作者调查了间接多巴胺激动剂d-苯丙胺(AMPH)对吸烟者线索诱导的烟瘾的影响。戒烟或未戒烟的吸烟者(N = 21)在接受AMPH(15毫克)或安慰剂预处理后,以及在观看与吸烟相关、与食物相关和中性图片组之前和之后,对香烟和食物(对照)的渴望程度进行了评分。在呈现线索之前,AMPH增加了对香烟的渴望并降低了对食物的渴望。吸烟和食物线索分别增加了对香烟和食物的渴望。在呈现线索后,AMPH也进一步增加了对香烟的渴望(并降低了对食物的渴望),但无论线索类型(食物或吸烟)如何均如此。无论线索呈现或药物状况如何,戒烟均显著增加了渴望程度。这些结果表明,AMPH和戒烟均可增加对香烟的渴望,但它们似乎并未特异性地影响对条件性吸烟相关线索的反应。
