Prefilled cartridges might be disposable or vapeakkutrager refillable. We determined the whole variety of unit gross sales of e-cigarettes, by flavoring sort (flavored, menthol, and regular), in 4-week aggregates. We used Joinpoint software program model 4.5.0.1 (Information Administration Systems, Inc) to check for dampfensale significance of discrete changes in trends in the percentages of sales (log-reworked), by flavor category, through the study period. Monitoring tobacco sales can complement self-reported surveillance methods to evaluate traits in tobacco use.

We used Joinpoint regression to assess trends. Menthol e-cigarette sales had been stable nationally at 35% to 40%, while the share of menthol disposable, ezigarettenneu prefilled cartridge, and e-liquid refill gross sales decreased. Use of a log-linear mannequin permits for evaluation of share change in each end result over time. For each e-cigarette product category, the AMPCs, which measure the relative change throughout the time period, had been assessed by yr and over the complete study interval.

For all e-cigarettes and for each of the 4 product categories, we decided the whole variety of unit gross sales, the proportion of flavored unit sales, the annual month-to-month proportion change (AMPC) in flavored unit gross sales, the percentage of menthol unit gross sales, and rabattvape the AMPC for menthol unit gross sales; we decided these values by yr for the research interval. Finally, for states, we calculated the percentages of flavored and menthol e-cigarette unit sales from 2012 by means of 2016 and vapeakkutrager for 2015-2016 and the AMPC for annually.

We aggregated information in 4-week intervals for the forty eight contiguous states and the District of Columbia for vapeimverkauf the 5-year period from 2012 by 2016. Data from vape outlets and internet sales weren't out there. The information include Common Product Code (UPC) sales from 2 distinct retail channels: convenience stores and all different shops combined. As a comparability, we determined the overall unit gross sales of combustible cigarettes, the percentage of menthol unit sales, and vapeakkutrager the AMPC for menthol items.

By state, menthol e-cigarette sales increased in 2 states (Idaho and Nebraska) and decreased in 7 states. This analysis evaluated data from January 15, 2012, vapebasen through January 7, 2017. Because we included solely 7 days in 2017, we refer to the study period as 2012-2016.
