Although research have documented increases in e-cigarette sales (17-19), this is the primary examine to evaluate latest nationwide and state trends in flavored and menthol e-cigarette product gross sales. These findings align with a current survey of greater than 4,000 grownup e-cigarette customers that concluded that the majority users transitioned to extra superior gadgets primarily for the purpose of obtaining a "more satisfying hit" (12).

However, present US tobacco surveys, vapezubehor such because the National Adult Tobacco Survey (13) and HealthStyles (14), vapekaufenonline don't gather data on the kind of e-cigarette used.

Given the quickly changing know-how of e-cigarettes, traits in e-cigarette use ought to be re-evaluated continuously, and surveillance measures ought to embrace the most recent and well-liked merchandise in the marketplace. Retail gross sales data can provide well timed info for monitoring the consumption of tobacco products by venue, product type, and brand.

Finally, for states, we calculated the percentages of flavored and ezigarettenonsale menthol e-cigarette unit gross sales from 2012 by means of 2016 and vapeeliquid for 2015-2016 and the AMPC for annually. Each e-cigarette UPC was assigned to one in every of 4 classes: 1) rechargeable e-cigarettes and e-cigarette starter kits (rechargeables), 2) disposable e-cigarettes (disposables), 3) cartridges prefilled with e-liquid (prefilled cartridges), and 4) bottles of e-liquid refills (e-liquids). UPCs corresponding to a number of items of differing flavors (eg, a starter package that features one menthol-flavored cartridge and one regular-flavored cartridge) could not be sorted reliably into one in every of the 3 flavor categories, elektrischenzigaretten so we excluded these from evaluation.

Closed-system e-cigarettes, additionally known as "cigalikes," require users to dispose of the e-liquid cartridge and replace it with a new, prefilled e-liquid cartridge.
