Introduction: New York (NY) implemented a statewide restriction on the retail sale of flavored vaping products to reduce availability of vaping products having youth-appealing flavors in 2020. We assessed the intended effects of the NY law on sales of flavored vaping products and explored whether policy implementation had unintended effects on consumer behavior by evaluating policy-associated changes in sales of combusted cigarettes, which could serve as more harmful substitute products for NY consumers of flavored vaping products.

Aims And Methods: We analyzed custom product-level weekly retail tobacco sales scanner data for NY and a comparison state (California [CA]) for convenience stores and other outlets from June 2018 through June 2021.

We assessed ENDS sales and prices at both the state and national level before and after JUUL's removal of mint flavors.

Introduction: Providence, Rhode Island (RI) was among the first US jurisdictions to enact a policy (effective 3 January 2013) restricting the retail sale of non-cigarette tobacco products with a characterising flavour other than the taste or aroma of tobacco, menthol, mint or wintergreen. We used scanner data to assess the impact of this sales restriction on retail availability of cigarillos, flavoured and otherwise, in Providence and a rest-of-state (ROS) comparison area.

Methods: Every unique cigarillo product-each indicated by a universal product code (UPC)-available for sale in RI from January 2012 to December 2016 was assigned to an exclusive flavour-name category (tobacco; explicit or concept flavour; or menthol/mint) based on characteristics in the scanner dataset and, as necessary, information from online websites.

Objective: This paper aims to (1) assess whether promotion of tax-free sales among Internet cigarette vendors (ICVs) changed between 2009 and 2011, (2) determine which types of ICVs are most likely to promote tax-free sales (eg, US-based, international or mixed location ICVs), and (3) compare the price of cigarettes advertised in ICVs to prices at brick-and-mortar retail outlets.

Methods: We analysed data from the 200 most popular ICVs in 2009, 2010 and 2011 to assess promotion of tax-free sales and the price of Marlboro cigarette cartons. We used Nielsen scanner data from 2009, 2010 and 2011 to measure the price of Marlboro cartons in US grocery stores.

This study estimated the effects of little cigar and cigarette prices on little cigar sales.
