Investigating the Impact of E-Cigarette Price and Tax on E-Cigarette Use Behavior.

Abstract

Although the relationship between tax and price and youth cigarette use is well established, little is known about these associations and youth e-cigarette use. This research examines U.S. youth sensitivity to changes in e-cigarette prices and tax using standardized measures of e-cigarette taxes and prices. This analysis uses national data on past 30-day use and the number of days using e-cigarettes (i.e., the intensity of use) from the repeat cross-sectional 2015-2019 Youth Risk Behavior Survey, in combination with inflation-adjusted standardized e-cigarette price and tax data to understand whether changes in e-cigarette price and tax were associated with changes in e-cigarette use. Two-part demand regression models controlling for demographics and e-cigarette restriction policies were conducted to calculate price and tax elasticities of demand, in addition to $0.50 and $1.00 price and tax increase simulations. Increased e-cigarette prices and taxes were associated with significant reductions in past 30-day use. Prices were also significantly associated with decreases in the intensity of use. A $0.50 and $1.00 tax increase leads to a 6.3% and 12.2% decrease in past 30-day use and a 4.7% and 9.3% decrease in intensity, respectively. A $0.50 and $1.00 price increase leads to a 4.1% and 8.2% decrease in past 30-day use and a 4.2% and 8.3% decrease in intensity, respectively. Higher prices and taxes reduce youth current e-cigarette use and days using e-cigarettes. Policies increasing e-cigarette prices, such as excise taxes, can reduce youth current e-cigarette use and days using e-cigarettes.
