简介：电子烟是变化很大的设备，通常具有用户可定义的液体和设备参数。然而，人们对普通用户如何操纵这些参数知之甚少。也有有限的理解是什么因素驱动电子烟的使用和液体购买，以及是否两个常见的成分，丙二醇和植物甘油，改变这些设备的主观效果。方法：在2016年春季522名成年人，谁报告每天使用的电子烟含有尼古丁，完成了一项调查。调查问题包括电子烟依赖问卷、烟草和电子烟使用问题以及设备和液体偏好。结果：59%的受访者报告使用另一种烟草产品，这与尼古丁依赖水平呈正相关。平均而言，器械设置为28.3（SD = 24.2）瓦。改变设备电压的能力和通常使用的电阻水平与尼古丁依赖水平显著相关。摄入的液体量、尼古丁浓度和每周使用的尼古丁毫克数与尼古丁依赖呈正相关。参与者将“好味道”评为使用和购买液体时最重要的考虑因素，丙二醇与不良影响和植物甘油与理想的effects.Conclusions：这些数据表明，电子烟使用者利用广泛的设备参数设置和液体变量，以及个人更大的尼古丁依赖有利于电压控制设备，和较低的电阻加热元件。口味是电子烟选择的关键因素，丙二醇和植物甘油的浓度可能对液体的增强效果有显著影响。
Introduction: Electronic cigarettes are widely variable devices, typically with user definable liquid and device parameters. Yet, little is known about how regular users manipulate these parameters. There is also limited understanding of what factors drive electronic cigarette use and liquid purchasing, and whether two common ingredients, propylene glycol and vegetable glycerin, alter the subjective effects of these devices.Methods: During the spring of 2016 522 adults, who reported daily use of electronic cigarettes containing nicotine, completed a survey on electronic cigarettes. Survey questions included an electronic cigarette dependence questionnaire, questions on tobacco and electronic cigarette use, and device and liquid preferences.Results: Fifty-nine percent of respondents reported using another tobacco product, which was positively associated with level of nicotine dependence. On average, devices were set to 28.3 (SD = 24.2) watts. Ability to change device voltage, and level of resistance typically used, was significantly associated with level of nicotine dependence. Amount of liquid consumed, nicotine concentration, and milligrams of nicotine used per week, were positively associated with nicotine dependence. Participants rated 'good taste' as the most important consideration when using and purchasing liquids, and propylene glycol is associated with undesirable effects and vegetable glycerin with desirable effects.Conclusions: These data indicate that electronic cigarette users utilize a wide range device parameter settings and liquid variables, and that individuals with greater nicotine dependence favor voltage control devices, and lower resistance heating elements. Taste is a key factor for electronic cigarette selection, and concentrations of propylene glycol and vegetable glycerin may have a significant impact on the reinforcing effects of liquids.
