Introduction
In September 2014, CVS Health ceased tobacco sales in all of its 7700
pharmacies nationwide. We investigate the impact of the CVS policy on the
number of cigarettes smoked per day among metropolitan daily and non-daily
smokers, who may respond to the availability of smoking cues in different
manners.
Methods Data
are from the US Census Bureau Tobacco Use Supplement to the Current Population
Survey 2014–2015 and the Blue Cross and Blue Shield Institute Community Health
Management Hub. Adjusted difference-in-difference (DID) regressions assess
changes in the number of cigarettes smoked per day among daily smokers
(n=10 759) and non-daily smokers (n=3055), modelling core-based statistical
area (CBSA) level CVS pharmacy market share continuously. To assess whether the
policy had non-linear effects across the distribution of CVS market share, we
also examine market share using tertiles.
Results
CVS’s tobacco-free pharmacy policy was associated with a significant reduction
in the number of cigarettes smoked by non-daily smokers in the continuous DID
(rate ratio=0.985, p=0.022), with a larger reduction observed among non-daily
smokers in CBSAs in the highest third of CVS market share compared with those
living in CBSAs with no CVS presence (rate ratio=0.706, p=0.027). The policy, however,
was not significantly associated with differential changes in the number of
cigarettes by daily smokers.
Conclusion
The removal of tobacco products from CVS pharmacies was associated with a
reduction in the number of cigarettes smoked per day among non-daily smokers in
metropolitan CBSAs, particularly those in which CVS had a large pharmacy market
share.
