Smoking related stimuli are known to increase both subjective craving and heart rate in smokers; however, little is currently known about the effects of such stimuli in former smokers.
Subjective craving and heart rate were measured in 38 never smokers, 20 former smokers, and 30 current smokers exposed to video clips containing neutral and smoking related cues.
Compared with neutral cues, smoking cues significantly increased both heart rate and self-reported craving in current smokers, while in former smokers smoking cues were associated with a significant decrease in heart rate as well as with a relatively diminished increase in subjective craving. Neither craving nor heart rate was impacted by the smoking cues in never smokers.
Findings suggest that while smoking related stimuli continue to elicit modest subjective cravings in former smokers, there appears to be a marked change in the typical physiological response associated with such stimuli.
已知与吸烟相关的刺激会增加吸烟者的主观渴望和心率；然而，目前对于此类刺激对曾经吸烟者的影响知之甚少。
对38名从不吸烟者、20名曾经吸烟者和30名当前吸烟者进行测试，让他们观看包含中性和与吸烟相关线索的视频片段，并测量其主观渴望和心率。
与中性线索相比，吸烟线索显著增加了当前吸烟者的心率和自我报告的渴望，而在曾经吸烟者中，吸烟线索与心率显著降低以及主观渴望的相对增幅减小有关。从不吸烟者的渴望和心率均未受到吸烟线索的影响。
研究结果表明，虽然与吸烟相关的刺激在曾经吸烟者中仍会引发适度的主观渴望，但与此类刺激相关的典型生理反应似乎发生了显著变化。
