The Effectiveness of Using
E‐cigarettes for Quitting Smoking Compared to Other
Cessation Methods among Adults in the United Kingdom.
Addiction, https://doi.org/10.1111/add.15474.
Background and aims. Evidence
on the effectiveness of electronic cigarettes (ECs) to facilitate abstinence
from smoking is limited. The current study aimed to estimate the relative
effectiveness of ECs and smoking cessation medication compared with using no
help, accounting for frequency of use of ECs.
Design. Four
consecutive wave‐to‐wave
transitions (waves 1‐2,
2‐3,
3‐4
or 4‐5)
of a longitudinal online survey collected between 2012 and 2017 were analysed.
Time between waves ranged between 12 and 17 months. Cigarette smokers at the
baseline wave who attempted to quit smoking between waves were included.
Setting. United
Kingdom
Participants. A
total of 1155 respondents (aged 18‐81, 56.1% male, 64.6% in
social grade C2DE, 93.8% white) provided 1580 pairs of observations for the
primary analysis.
Measurements. Primary
outcome: abstinence from smoking for at least 1 month at follow‐up;
secondary outcome: at least 1 month’s abstinence from smoking between baseline
and follow‐up.
The main predictor was stop smoking aid used (No help, nicotine replacement
therapy only, smoking cessation medication only, disposable/cartridge EC,
refill/modular EC, combination), adjusted for demographics.
Findings, Primary. Compared
with using no help, the odds of abstinence were increased by daily use of
disposable/cartridge ECs (OR=3.31 (1.32, 8.26), p=.010) and daily use of
refill/modular ECs (OR=5.47 (2.70, 11.11), p<.001). Odds were reduced by non‐daily
use of disposable/cartridge ECs (OR=0.23 (0.08‐0.63),
p=.005), and by use of disposable/cartridge ECs to quit and no longer using at
follow‐up
(OR=0.10 (0.16‐0.62),
p<.013). Secondary Results were similar to the primary outcome; however,
odds of abstinence were also increased by use of smoking cessation medication
(OR=4.15 (1.79, 9.62), p=.001).
Conclusions.
When used daily, electronic cigarettes appear to facilitate abstinence from
smoking when compared with using no help.
