Objectives: Measurement of electronic cigarette (ECIG) puff topography provides an under- standing of how product characteristics and user behavior affect nicotine delivery. However, mouthpiece-based topography devices may affect natural puffing behavior. This study was designed to compare ECIG topography measured by mouthpiece-based eTop computerized de- vice and mouthpiece-free video recordings. Methods: ECIG-naïve cigarette smokers (N = 18) and ECIG-experienced users (N = 25) puffed on a standardized ECIG via eTop or conventionally; both sessions were videotaped. Following overnight abstinence, participants experienced one directed (10 puffs, 30 sec IPI) and 2 ad libitum puffing bouts. Heart rate and subjective response were measured throughout sessions. Results: No statistically significant differences between methods were observed for topography, heart rate, or abstinence-related subjective effects, and both methods were accurate and reliable. Use of a mouthpiece was perceived to alter aspects of ECIG puffing (eg, "reduce enjoyment). Conclusions: The mouthpiece-based eTop measures ECIG topography precisely as when no mouthpiece is used, and interferes minimally with subjective ECIG experience. Reliable and valid ECIG topography measurement methods are an important regulatory tool, as they can be used to understand the interplay between product design and user behavior to predict toxicant exposure.

More about this publication?
  • Tobacco Regulatory Science (Electronic ISSN 2333-9748) is a rigorously peer-reviewed online scientific journal for the dissemination of research relevant to the regulation of tobacco products. The journal content includes a broad array of research domains, including chemistry, biology, behavior, community, and population-level surveillance and epidemiology, as well as knowledge syntheses (eg, meta-analyses or state-of-the-art reviews) and analytic modeling. All articles describe the policy relevance of the research outcomes. Given the global nature of tobacco regulation, particularly as a result of international and national policies, Tobacco Regulatory Science publishes high quality research that is relevant to global regulatory needs and requirements. Tobacco Regulatory Science is published electronically 6 times per year.
