BackgroundCalifornia raised cigarette excise taxes in 1999, and may generate additional health and economic benefits by raising them further.MethodsA dynamic computer simulation model follows births, deaths, migration, aging, and changes in smoking status for the entire population of California over 75 years to estimate the cumulative health and economic outcomes of these changes under several excise tax rate conditions (up to 100% price increase).ResultsA 20% tax-induced cigarette price increase would reduce smoking prevalence from 17% to 11.6% with large gains in cumulative life years (14 million) and QALY's (16 million) over 75 years. Total spending on cigarettes by consumers would increase by 270 million dollars in that span (all going to tax revenue), and those who reduce the number of years spent as a smoker would spend 12.5 billion dollars less on cigarettes. Total smoking-related medical costs would drop by 188 billion dollars. These benefits increase greatly with larger tax increases, with which tax revenues continue to rise even as smoking prevalence falls.ConclusionsEven considering benefits from the 1999 increase, California has not yet maximized the potential of excise taxes to lessen the negative impacts of smoking. Additional tax increases would provide added health benefits and revenue to the state.
