Circadian Puffing Behavior and Topography Among E-cigarette Users.

ABSTRACT:

Objectives

The aim of this study was to examine puffing behavior and topography over 24 hours among regular electronic cigarette (e-cigarette) users.

Methods

Twenty-four adult e-cigarette users (15 male) vaped their personal e-cigarettes ad-lib over the course of 24 hours. Participants took each puff via calibrated CReSS pocket topography monitors. We analyzed: number of puffs per day per session, mean puff volume, mean puff flow rate, mean duration of puff, and mean interval between puffs.

Results

Over 24 hours participants took on average 156.2±10.3 puffs, clustered in 10.2±7.9 puffs per puffing session with an average puff interval of 15.4±22.0 sec. A single puff lasted on average 3.0±1.2 sec, had a volume of 73.4±51.5 ml, and was taken with the average flow rate o
