Each e-cigarette UPC was assigned to one in all four classes: 1) rechargeable e-cigarettes and e-cigarette starter kits (rechargeables), 2) disposable e-cigarettes (disposables), liquidmischen 3) cartridges prefilled with e-liquid (prefilled cartridges), and 4) bottles of e-liquid refills (e-liquids). From 2012 by 2016, flavored e-cigarette sales as a proportion of all e-cigarette gross sales elevated nationally (from 2.4% to 19.8%) and in all however four states (North Dakota, South Dakota, Utah, and Vermont).

Continued monitoring of sales traits at all retail shops can inform federal, state, and native efforts to address flavored tobacco product use, liquidsaromen together with e-cigarettes, within the United States. Monitoring tobacco gross sales can complement self-reported surveillance strategies to evaluate trends in tobacco use. We used Joinpoint regression to evaluate tendencies. Menthol e-cigarette sales had been stable nationally at 35% to 40%, vapezubehor while the share of menthol disposable, prefilled cartridge, and dampfkit e-liquid refill gross sales decreased.

Use of a log-linear mannequin allows for analysis of proportion change in each end result over time. For each e-cigarette product class, the AMPCs, which measure the relative change during the time period, were assessed by 12 months and dampferaromen over the full research interval. For all e-cigarettes and for each of the four product categories, we determined the full variety of unit sales, the proportion of flavored unit sales, the annual monthly percentage change (AMPC) in flavored unit sales, the percentage of menthol unit gross sales, vapemischen and the AMPC for menthol unit gross sales; we decided these values by 12 months for the research interval.

Finally, for states, we calculated the percentages of flavored and menthol e-cigarette unit gross sales from 2012 by way of 2016 and for vapezubehor 2015-2016 and the AMPC for annually.

We aggregated knowledge in 4-week intervals for the forty eight contiguous states and the District of Columbia for the 5-year interval from 2012 via 2016. Data from vape shops and web gross sales were not accessible.
