Short-Term Impact of a Flavored Tobacco Restriction: Changes in Youth Tobacco Use in a Massachusetts Community.

INTRODUCTION: To counter the high prevalence of flavored tobacco use among youth, many U.S. localities have passed policies that restrict youth access to these products. This study aims to evaluate the short-term impact of a flavored tobacco restriction policy on youth access to, and use of, flavored tobacco products in a Massachusetts community. METHODS: A community with the policy (Lowell) was matched to a community without the policy (Malden) with similar demographics, retailer characteristics, and point-of-sale tobacco policies. Product inventories were assessed in tobacco retailers in the 2 communities, and surveys were administered to high school-aged youth in those communities. Inventories and surveys were conducted around the time the policy took effect in October 2016 (baseline) and approximately 6 months later (follow-up); all data were analyzed in 2017. Chi-squared tests and difference-in-difference models were used to estimate the impact of the policy on flavored tobacco availability and youth perceptions and behaviors related to flavored tobacco use. RESULTS: Flavored tobacco availability decreased significantly in Lowell from baseline to follow-up periods by 70 percentage points (p<0.001), whereas no significant changes in flavored tobacco availability were seen in Malden. In addition, current use of both flavored and non-flavored tobacco decreased in Lowell, but increased in Malden from baseline to follow-up; these changes were significantly different between communities (flavored tobacco: -5.7%, p=0.03; non-flavored tobacco: -6.2%, p=0.01). CONCLUSIONS: Policies that restrict the sale of flavored tobacco have the potential to curb youth tobacco use in as few as 6 months.
