Introduction. In
2019, an outbreak of e-cigarette, or vaping, product use-associated lung injury
(EVALI) occurred in the US. We used Nielsen retail sales data to assess trends
in sales of e-cigarettes, cigarettes, and nicotine replacement therapy (NRT)
products before, during, and after the EVALI outbreak.
Methods. Monthly
unit sales of e-cigarettes, cigarettes, and NRT products overall and by product
type were assessed during January 2019 through June 2020 by using an
interrupted time series model. Two time points were specified at the period
ending July 13, 2019, and the period ending February 22, 2020, to partition
before, during, and after the outbreak period. Sales trends by aggregated
state-level EVALI case prevalence (low, medium, and high) were assessed to
investigate interstate variations in changes of sales coinciding with the EVALI
outbreak.
Results. Monthly
e-cigarette sales increased 3.5% (P < .001) before the outbreak and
decreased 3.1% (P < .001) during the outbreak, with no significant changes
after the outbreak. Monthly cigarette sales increased 1.6% (P < .001) before
the outbreak, decreased 1.8% (P < .001) during the outbreak, and increased
2.7% (P < .001) after the outbreak. NRT sales did not change significantly
before or during the outbreak but decreased (2.8%, P = .01) after the outbreak.
Sales trends by state-level EVALI case prevalence were similar to
national-level sales trends.
Conclusion. Cigarette
and e-cigarette sales decreased during the EVALI outbreak, but no changes in overall
NRT sales were observed until after the outbreak. Continued monitoring of
tobacco sales data can provide insight into potential changes in use patterns
and inform tobacco prevention and control efforts.
