In total, 3.2% of American adults report using e-cigarettes every day or some days. The Vaping and Patterns E-cigarette Use Research (VAPER) Study is a web-based longitudinal survey designed to observe patterns in device liquid use that suggest the benefits unintended consequences potential e-cigarette regulations. heterogeneity devices liquids on market, customizability liquids, lack standardized reporting requirements result unique measurement challenges. Furthermore, bots takers who...
e-Cigarette device and liquid characteristics are highly customizable; these impact nicotine delivery exposure to toxic constituents. It is critical understand optimal methods for measuring accurately assess their impacts on user behavior health.
Electronic nicotine delivery system (ENDS) device and liquid characteristics (e.g., wattage, concentration) are diverse important in determining product appeal, aerosol volume/nicotine levels, toxicity. Little is known about how vary by flavor; we address this gap to identify potential regulatory implications.
In 2019, we launched a web-based longitudinal survey of adults who frequently use e-cigarettes, called the Vaping and Patterns E-cigarette Use Research (VAPER) Study. The initial attempt to collect data failed due fraudulent submissions, likely submitted by bots other takers. This paper chronicles journey from that setback successful completion 5 waves collection. section “Naïve Beginnings” examines study preparation phase, identifying events, decisions, assumptions contributed failure (eg,...
Electronic nicotine delivery system (ENDS) and liquid characteristics affect toxicant exposure use behaviors. Little is known about how adults who frequently ENDS transition between device/liquid groupings.A total of 379 US (≥21 years) using (≥5 days/week) self-reported uploaded photos their most used device in three waves online surveys (May 2020 - November 2021). Device/liquid grouping was defined by (i.e. disposable/refillable tank/refillable pod or cartridge/disposable cartridge,...
Longitudinal cohort studies are critical for understanding the evolution of health-influencing behaviors, such as e-cigarette use, over time. Optimizing follow-up rates in longitudinal is necessary ensuring high-quality data with sufficient power analyses. However, achieving high web-based can be challenging, even when monetary incentives provided.
The electronic nicotine delivery systems (ENDS) market is heterogeneous with a wide variety of devices and liquids available to consumers. People distinct sociodemographic characteristics may have different ENDS device liquid preferences. 1290 U.S. adults (21 + ) using 5 days/week completed the Wave (February-April 2023) VAPER study survey submitted photos their most used liquid. Latent class analysis (LCA) was performed based on cigarette smoking status identify groups among respondents. We...
Electronic nicotine delivery systems (ENDS) use one of two formulations nicotine-freebase or salt. This study examines whether maintenance switching between is associated with ENDS dependence using longitudinal survey data.

Background: The electronic nicotine delivery systems (ENDS) market is highly heterogeneous. People with distinct sociodemographic characteristics may have different ENDS device and liquid preferences. Methods: 1290 U.S. adults (21+) using 5+ days/week completed the Wave 5 (February-April 2023) VAPER study survey submitted photos of their most used liquid. latent class analysis (LCA) was performed based on cigarette smoking status to identify classes among these respondents. We examined...
