abstract = {INTRODUCTION Few studies to date have characterized daily exclusive
e-cigarette users, device characteristics, and use behaviors. This study
describes daily e-cigarette user characteristics, and assesses the association
between user behaviors and demographics.
METHODS From 2015–2017, 100 daily exclusive e-cigarette users and 50 nonusers
were recruited in Maryland, USA. Sociodemographic characteristics,
health status, e-cigarette/tobacco use behaviors, device characteristics,
and reasons for e-cigarette use were collected by interview. Chi-squared
tests (categorical variables), Student’s t-test (continuous variables), and
linear regressions were used to assess relationships between variables.
RESULTS Most daily exclusive e-cigarette users were men, White, former
smokers, used MODs/tanks, and vaped on average 365 puffs/day (SD:
720). A third of users first vaped within 5 minutes of waking in the
morning, and 56% vaped throughout the day. E-liquid consumption
ranged from 5–240 mL/week (median: 32.5), with nicotine concentration
0–24 mg/mL (median: 3). E-cigarette users were more likely to report
wheezing/whistling and hypertension than controls, although the finding
was not statistically significant after adjustment. Less than half planned
to quit vaping.
CONCLUSIONS Daily e-cigarette users between 2015–2017 most commonly
vaped MOD/tank devices. Being male and of lower education was
associated with higher usage. Daily users with no intention to quit may be
at risk for increased exposure to emissions from e-cigarettes that include
inorganic (metals) and organic (e.g. acrolein, formaldehyde) compounds
with known toxic effects, particularly to the lung. Further research is
needed to characterize the long-term health effects of daily e-cigarette
use},
