Electronic cigarette (e-cigarette) use continues to proliferate with fast-paced product evolution. Pod mod e-cigarettes emerged in the market in 2015 and have changed the tobacco landscape again. However, little is known regarding their addiction potential among users. The current study describes e-cigarette dependence and demand among pod mod users as a function of smoking status (current smokers/dual users, former smokers, and never smokers). Participants were 593 young adult ( = 25.9 years) JUUL users recruited via Amazon's Mechanical Turk. Respondents were specifically recruited based on current use of pod mods (but may also be using other e-cigarette devices) and smoking status (never, former, and current/dual users). Participants completed online measures assessing e-cigarette dependence and demand. Dual users of pod mods and cigarettes displayed greater e-cigarette dependence compared to current pod mod users with no history of cigarette smoking ( = .033). Similarly, dual users showed the greatest levels of e-cigarette demand compared to both former smokers and those without a history of smoking (s < .05). Dual users displayed the greatest e-cigarette dependence and demand. Future research should directly assess potential mechanisms for this effect and continue to monitor e-cigarette dependence as the tobacco landscape changes with the emergence of new e-cigarette products and innovations.

电子烟（e-cigarette）的使用随着产品的快速发展而不断普及。一次性电子烟于 2015 年出现在市场上，再次改变了烟草格局。然而，对于使用者的成瘾潜力，人们知之甚少。本研究描述了一次性电子烟使用者对电子烟的依赖和需求，将其作为吸烟状况（当前吸烟者/双重使用者、前吸烟者和从不吸烟者）的一个函数。参与者是通过亚马逊的 Mechanical Turk 招募的 593 名年轻成年人（=25.9 岁）JUUL 用户。根据目前使用一次性电子烟（也可能同时使用其他电子烟设备）和吸烟状况（从不吸烟、前吸烟者和当前/双重使用者），专门招募了受访者。参与者完成了在线评估电子烟依赖和需求的测量。与没有吸烟史的当前一次性电子烟使用者相比，双重使用者（即同时使用电子烟和香烟）表现出更强的电子烟依赖（=0.033）。同样，与前吸烟者和不吸烟者相比，双重使用者表现出最大的电子烟需求水平（s<0.05）。双重使用者表现出最大的电子烟依赖和需求。未来的研究应该直接评估这种影响的潜在机制，并随着新的电子烟产品和创新的出现，继续监测电子烟的依赖情况，因为烟草格局正在发生变化。
