{Reference Type}: Journal Article {Title}: Tobacco Retail Sales in Massachusetts and New Hampshire Before and After Massachusetts' Flavored Tobacco Restriction. {Author}: McGinnes H;Kingsley M;Song G;Doane J;Henley P; {Journal}: J Public Health Manag Pract {Volume}: 30 {Issue}: 4 {Year}: 2024 Jul-Aug 1 {Factor}: 2.657 {DOI}: 10.1097/PHH.0000000000001869 {Abstract}: In June 2020, Massachusetts became the first state to implement a comprehensive flavored tobacco restriction. One concern was that Massachusetts residents would travel to New Hampshire to purchase restricted products. This article assesses tobacco sales in both states post-law implementation. Retail scanner data were obtained from the Nielsen Company and Information Resources, Inc (IRI), from 1 year pre-law implementation to 2 years post-law implementation. Data post-law implementation were compared with data from 1 year pre-law implementation (baseline). In Massachusetts, 2 years post-law implementation, flavored and menthol tobacco sales decreased by more than 90%. Total sales decreased by around 20%. In New Hampshire, menthol tobacco sales increased (25.1% in IRI and 18.2% in Nielsen), but total sales changed minimally (<5% increase in IRI, <5% decrease in Nielsen). When data from both states were combined, total sales decreased by around 10%. The net decrease in total tobacco sales across Massachusetts and New Hampshire indicates Massachusetts' flavored tobacco restriction resulted in a reduction in tobacco sales despite potential cross-border purchases.
