Association of a major tobacco tax increase in California with increased smoking cessation
Menée à l'aide de données américaines portant sur 443 054 personnes ayant fumé dans les 12 derniers mois, cette étude analyse l'effet, sur le nombre de personnes ayant arrêté de fumer, de la "Proposition 56" qui augmente la taxe sur les cigarettes ainsi que les subventions pour la prévention du tabagisme
In November 2016, California voters approved Proposition 56, increasing the cigarette tax by $2.00 per pack and nearly tripling spending on tobacco prevention. This study examined whether the initiative was associated with increased smoking cessation.States in the United States were categorized into 3 groups: California, 18 other states (including the District of Columbia) that raised taxes, and 32 states that did not raise taxes. Tax and price increases, tobacco prevention spending per capita, 3-month smoking cessation rates using data from the Behavioral Risk Factor Surveillance System (N = 443 054), and the proportion of daily smoking were compared for 2014-2016 and 2017-2019 for these groups.California had the largest increases in cigarette price (30.8%) and tobacco prevention spending (271.9%), both adjusted for inflation. Other states that raised taxes experienced price increases of 6.3% on average. The 3-month smoking cessation rate in California increased from 11.5% in 2014-2016 to 14.2% in 2017-2019 (P = .005). Among other states that raised taxes in that timeframe, cessation rates did not change significantly, from 8.6% to 8.7% (P = .755). Among states that did not raise taxes, cessation rates declined significantly, from 9.5% to 9.0% (P = .026). California also had a significant reduction in the proportion of daily smokers among those who did not quit (from 60.4% to 56.4%, P = .012).A major cigarette tax increase was associated with increased smoking cessation in California. Policies increasing tobacco taxes and re-investing new revenue in tobacco prevention can increase population cessation.
