Background: In response to the recent government restrictions, flavored JUUL products, which are rechargeable closed-system electronic cigarettes (e-cigarettes), are no longer available for sale. However, disposable closed-system products such as the flavored Puff Bar e-cigarette continues to be available. If e-cigarette consumers simply switch between products during the current government restrictions limited to 1 type of product over another, then such restrictions would be less effective. A step forward in this line of research is to understand how the public discusses these products by examining discourse referencing both Puff Bar and JUUL in the same conversation. Twitter data provide ample opportunity to capture such early trends that could be used to help public health researchers stay abreast of the rapidly changing e-cigarette marketplace. Objective: The goal of this study was to examine public discourse referencing both Puff Bar and JUUL products in the same conversation on Twitter. Methods: We collected data from Twitter’s streaming application programming interface between July 16, 2019, and August 29, 2020, which included both “Puff Bar” and “JUUL” (n=2632). We then used an inductive approach to become familiar with the data and generate a codebook to identify common themes. Saturation was determined to be reached with 10 themes. Results: Posts often mentioned flavors, dual use, design features, youth use, health risks, switching 1 product for the other, price, confusion over the differences between products, longevity of the products, and nicotine concentration. Conclusions: On examining the public’s conversations about Puff Bar and JUUL products on Twitter, having described themes in posts, this study aimed to help the tobacco control community stay informed about 2 popular e-cigarette products with different device features, which can be potentially substituted for one another. Future health communication campaigns may consider targeting the health consequences of using multiple e-cigarette products or dual use to reduce exposure to high levels of nicotine among younger populations.

Twitter 上关于 JUUL 和 Puff Bar 产品的主要话题：内容分析

背景：为应对近期政府的限制，作为可充电封闭系统电子烟（e-香烟）的调味 JUUL 产品不再销售。然而，一次性封闭系统产品，如风味 Puff Bar 电子烟，继续可用。如果电子烟消费者在当前政府对一种产品的限制期间简单地在产品之间切换，那么这种限制将不太有效。这方面的研究向前迈出的一步是通过检查在同一对话中同时引用 Puff Bar 和 JUUL 的话语来了解公众如何讨论这些产品。Twitter 数据为捕捉此类早期趋势提供了充足的机会，可用于帮助公共卫生研究人员跟上快速变化的电子烟市场。目标：本研究的目标是检查在 Twitter 上的同一对话中引用 Puff Bar 和 JUUL 产品的公共话语。方法：我们在 2019 年 7 月 16 日至 2020 年 8 月 29 日期间从 Twitter 的流应用程序编程接口收集数据，其中包括“Puff Bar”和“JUUL”（n=2632）。然后我们使用归纳方法来熟悉数据并生成一个码本来识别共同的主题。饱和度被确定为达到 10 个主题。结果：帖子经常提到口味、双重用途、设计特点、年轻使用、健康风险、将一种产品换成另一种、价格、混淆产品之间的差异、产品的寿命和尼古丁浓度。结论：通过检查 Twitter 上公众关于 Puff Bar 和 JUUL 产品的对话，在帖子中描述了主题，本研究旨在帮助烟草控制社区了解具有不同设备功能的 2 种流行电子烟产品，这些产品可能被替代为彼此。未来的健康宣传运动可能会考虑针对使用多种电子烟产品或双重使用的健康后果，以减少年轻人接触高水平尼古丁的风险。这项研究旨在帮助烟草控制社区了解 2 种具有不同设备功能的流行电子烟产品，它们可以相互替代。未来的健康宣传运动可能会考虑针对使用多种电子烟产品或双重使用的健康后果，以减少年轻人接触高水平尼古丁的风险。这项研究旨在帮助烟草控制社区了解 2 种具有不同设备功能的流行电子烟产品，它们可以相互替代。未来的健康宣传运动可能会考虑针对使用多种电子烟产品或双重使用的健康后果，以减少年轻人接触高水平尼古丁的风险。
