INTRODUCTION: A rapidly growing number of U.S. employers are charging health insurance surcharges for tobacco use to their employees. Despite their potential to price-discriminate, little systematic empirical evidence of the impacts of these tobacco surcharges has been published. We attempted to assess the impact of a health insurance surcharge for tobacco use on cessation among enrollees in Georgia's State Health Benefit Plan (GSHBP). METHODS: We identified a group of enrollees in GSHBP who began paying the tobacco surcharge at the program's inception in July 2005. We examined the proportion of these enrollees who certified themselves and their family members as tobacco-free and no longer paid the surcharge through April 2011, and we defined this as implied cessation. We compared this proportion to a national expected annual 2.6% cessation rate. We also compared our observation group to a comparison group to assess surcharge avoidance. RESULTS: By April 2011, 45% of enrollees who paid a tobacco surcharge starting in July 2005 had certified themselves as tobacco-free. This proportion exceeded the expected cessation based on 3 times the national rate (p < .001). The length of enrollment was not statistically different between our observation and comparison groups (p = .427). CONCLUSIONS: The reported rates of tobacco cessation among GSHBP enrollees resulting from a tobacco surcharge substantially exceed national rates. These surcharges appear to be effective, but the value of these results, and the effectiveness of health insurance surcharges in changing behavior, are tempered by the important limitation that enrollees' certification of quitting was self-reported and not subject to additional, clinical verification.
