Summary
Introduction:
This article reports a study on the puffing topography and nicotine intake of electronic cigarette (EC) users. The study aims to understand EC use and nicotine intake by evaluating EC topography parameters using two EC brands and calculating nicotine intake for each user and each brand. The study also validates the Clinical Research Support System (CReSS Pocket) for EC use.
Key Points:
* The study used two EC brands, Blu Cigs and V2 Cigs, and evaluated topography parameters, including puff duration, puff count, volume, flow rate, peak flow, and inter-puff interval.
* The CReSS Pocket device was validated for EC use by testing pressure drop, flow rate, and volume.
* The study found that puff duration, inter-puff interval, and puff volume varied from conventional cigarette standards.
* Nine patterns of EC use were identified, and individual users often showed consistency in multiple areas of EC puffing topography.
* Fluid consumption varied among users, with no significant difference between brands.
* The average nicotine intake for Blu and V2 across both sessions was similar to conventional smokers.
* The study highlights the need for a standard protocol for laboratory testing of EC products.
Main Message:
The study provides valuable information on EC topography and nicotine intake, which can contribute to the development of a standard protocol for laboratory testing of EC products. The study also demonstrates the need for further research on EC topography to better understand potential health risks and inform regulatory measures. Overall, the study emphasizes the importance of regulating EC products to protect public health.
