E-cigarette and tobacco product use among NYS youth before and after a state-wide vaping flavour restriction policy, 2020-2021

SignificanceReducing youth e-cigarette use is a New York State (NYS) public health priority. In May 2020, a state-wide restriction on flavoured e-cigarettes, except tobacco flavour, was passed. This study examines changes in nicotine product use behaviour among youth around the time of the state-wide vaping flavour restriction. MethodsNYS data from the US International Tobacco Control Policy Evaluation Project Youth Tobacco and E-cigarette Tobacco and Vaping Survey were analysed cross-sectionally from February 2020 (n=955), August 2020 (n=946), February 2021 (n=1030) and August 2021 (n=753). Online surveys were conducted among youth 16-19 years. Weighted descriptive statistics and regression models were used to describe changes in nicotine product use behaviour. Models were adjusted for age, sex, race/ethnicity and perceived family socioeconomic status. ResultsSignificant decreases in past 30-day e-cigarette use (20%-11%), cigarette (7%-4%), and dual use of e-cigarettes and cigarettes (5%-2%) were observed over the 2-year period in NYS. Over 95% of vapers still reported using a non-tobacco-flavoured e-cigarette following the restriction, with fruit-flavoured being the most popular at each time point. ConclusionsNearly all NYS youth continued to vape flavours that were restricted in NYS. While youth past 30-day vaping prevalence decreased significantly from 2020 to 2021, increased flavour restriction compliance could result in an even greater decrease. Continuous monitoring is important to better understand perceptions, use patterns and access at the individual level, retail level and population level to inform future enforcement and restrictions.
