Steeper delay discounting in substance abuse populations, compared to non-abusing populations, has been well-established in prior studies. Despite the growing interest in e-cigarettes as a novel and relatively understudied form of nicotine consumption, relatively little is known as to how e-cigarette users discount rewards compared to traditional cigarette smokers and never smokers. In the present study, we measured delay and probability discounting rates, as well as perceived risk inherent to a delayed reward, in current traditional cigarette smokers, e-cigarette users, and never smokers. We found that traditional cigarette smokers and e-cigarette users discounted delayed rewards at a similar rate-and both were steeper than never smokers. However, no differences were observed in probability discounting or in perceived risk inherent in reward delay.
与非滥用人群相比，药物滥用人群中更严重的延迟折扣现象在先前的研究中已得到充分证实。尽管电子烟作为一种新颖且相对研究较少的尼古丁消费形式越来越受到关注，但与传统吸烟者和从不吸烟者相比，电子烟使用者如何对奖励进行折扣却知之甚少。在本研究中，我们测量了当前传统吸烟者、电子烟使用者和从不吸烟者的延迟和概率折扣率，以及延迟奖励所固有的感知风险。我们发现，传统吸烟者和电子烟使用者对延迟奖励的折扣率相似，且两者都比从不吸烟者更严重。然而，在概率折扣或奖励延迟所固有的感知风险方面未观察到差异。
