Real-Time Characterization of E-Cigarettes Use: The 1 Million Puffs Study

Introduction:
This article by Dautzenberg and Bricard presents an analysis of data from a connected electronic cigarette (Smokio®) and its use by 185 users over a period of 116 days. The study aims to provide real-world data on the use of electronic cigarettes, which can be useful for setting parameters for standardizing the characterization of electronic cigarette emissions. The study focuses on three parameters recorded by the device: identification of the device, exact time of initiation of a puff, and duration of the puff in milliseconds.

Key Points:

* The study analyzed 1 million puffs generated by the Smokio® device.
* The median number of puffs per user was 5,405, and the mean puffs number by user/day was 163±138.
* The number of puffs per day decreased significantly on weekends compared to weekdays (-4.60%; p<0.001).
* The mean puff duration increased from 3.40±1.33s the first day of use to 4.11±1.55s after 60 days (p<0.001).
* The mean duration of puffs is higher for isolated puffs (4.57±2.24s) than for series >15 puffs (3.20±1.61s) (p<0.001).
* During the first 60 days of use, the rate of isolated puffs increased from 8.14% to 11.25% (p<0.001), and the mean number of puffs by series decreased from 6.78.±8.13 to 4.66±5.07 (p<0.001).
* The study provides real-world data on the use of electronic cigarettes that can be useful for setting parameters for standardizing the characterization of electronic cigarette emissions.

Main Message:
The study's main message is that the analysis of real-world data from a connected electronic cigarette can provide valuable insights into the use of electronic cigarettes. The study's findings can help set parameters for standardizing the characterization of electronic cigarette emissions in a group of French ENDS users. The study highlights the need for further research in this area to better understand the use of electronic cigarettes and their potential impact on public health.
