E-cigarette use is prohibited in most smoke-free environments. The effect of this policy on tobacco consumption could be examined using the Experimental Tobacco Marketplace (ETM). The ETM allows observation of policy on smokers' purchasing behavior under conditions that simulate "real-world" circumstances. A within-subject design was used to evaluate the effect of workplace policy (Vaping Allowed vs. Not Allowed) and nicotine concentration (24 mg/mL vs. 0 mg/mL) on tobacco product consumption. Participants (n = 31) completed one sampling and two ETM/workplace sessions per week for 2 weeks. During the sampling session, participants were given an e-cigarette with a 2-day supply of a commercially available e-liquid of their preferred flavor. Before purchasing, participants were informed whether e-cigarette use was permitted. During the four ETM sessions, participants purchased for the following 24 hr, including the 4-hr work shift that started immediately after buying products in the ETM. The workplace session consisted of data entry tasks in a mock office environment. Participants could use any purchased tobacco products during two 15-min breaks. Condition order was counterbalanced. The results show that permitting E-cigarette use in the workplace increased e-liquid purchase on average, but nicotine concentration had no effect on e-liquid demand. Cigarette demand was unaltered across conditions. The present study suggests that allowing e-cigarette use in the workplace would increase demand for e-liquid regardless of nicotine strength. However, it would not change conventional cigarette demand. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
电子烟在大多数禁烟环境中都是禁止使用的。可以通过实验性烟草市场（ETM）来检验这一政策对烟草消费的影响。ETM 允许在模拟“真实世界”情况下观察政策对吸烟者购买行为的影响。采用被试内设计来评估工作场所政策（允许电子烟使用与不允许电子烟使用）和尼古丁浓度（24 毫克/毫升与 0 毫克/毫升）对烟草制品消费的影响。参与者（n = 31）每周完成一次抽样和两次 ETM/工作场所测试，为期两周。在抽样测试中，参与者获得了一支电子烟，其中包含两天供应的他们所喜欢口味的商业电子烟液。在购买之前，参与者被告知是否允许使用电子烟。在四个 ETM 测试中，参与者购买了可在 24 小时内使用的产品，包括购买 ETM 产品后立即开始的 4 小时工作轮班。工作场所测试包括在模拟办公室环境中完成数据输入任务。参与者可以在两个 15 分钟的休息时间内使用任何购买的烟草制品。条件顺序是平衡的。结果表明，允许在工作场所使用电子烟会增加电子烟液的平均购买量，但尼古丁浓度对电子烟液的需求没有影响。无论条件如何，香烟的需求都没有改变。本研究表明，允许在工作场所使用电子烟将增加电子烟液的需求，无论尼古丁强度如何。然而，它不会改变传统香烟的需求。
