From the Heartland Institute:

In a 2017 Policy Study published by the R Street Institute, Associate Fellow Richard B. Belzer examined the potential financial impact to Medicaid costs in a scenario in which varying degrees of Medicaid recipients switch from using combustible tobacco cigarettes to electronic cigarettes or vaping devices.27 Belzer used a sample size of “1% of smokers [within] demographic groups permanently” switching. Using this analysis, Belzer estimated Medicaid savings “will be [in 25 years] approximately $2.8 billion per 1 percent of enrollees” who switch.

Additionally, research by Dr. Edward Anselm, a senior fellow for the R Street Institute and senior fellow and medical director of Health Republic Insurance of New Jersey, concludes the presence of flavorings in e-cigarettes significantly helps smokers quit using traditional tobacco cigarettes.89 Anselm also notes concerns over “flavoring as a tool to recruit children are overblown,” in large part because there is no “evidence that suggests children are drawn to tobacco products specifically because of flavor.”
