Electronic cigarette liquid and device parameters and aerosol characteristics: a survey of regular users

Introduction: This text provides an analysis of the regulatory implications of electronic nicotine delivery systems (ENDS), specifically focusing on electronic cigarettes (ECs). The reader will learn about the design and usage patterns of ECs, the factors affecting their nicotine delivery, and their potential health risks. The text also discusses the motivations for EC use and the role of flavors and throat hit in their appeal.

Key Points:

* ECs have many adjustable parameters, including heating element control, heater coil configurations, and refillable tanks for liquid composition.
* Nicotine concentration and puff topography in ECs can impact the nicotine delivery and plasma nicotine levels.
* Variables such as liquid container design, heating element parameters, liquid composition, and usage behaviors can affect the level of nicotine emitted by ECs and their potential harm.
* Taste and throat hit are significant factors driving both the initiation and continued use of ECs.
* a survey of regular nicotine-dispensing EC users in the United States was conducted to determine how adjustable parameters are typically used, the factors that motivate EC liquid selection, and the factors that influence initiation and continued EC use.
* Nicotine dependence was positively associated with frequency of EC use, adjustable settings, and liquid preferences.
* There is a need for more reliable approaches to determining common EC parameter settings and for future research to closely monitor changes in power settings and their impact on potentially harmful chemicals in EC aerosols.

Main Message: Understanding the usage patterns, nicotine delivery, and potential health risks of ECs is crucial for constructing relevant regulatory policy and maximizing their efficacy for smoking cessation. The survey results emphasize the importance of considering nicotine dependence, device parameters, and liquid preferences in developing regulations for ECs. Furthermore, the findings underscore the need for continued research on ECs to inform public health policy efforts and ensure the safety and efficacy of these devices for smokers seeking to quit.
