Tobacco Quitlines May Help Exclusive Vapers Quit: An Analysis of Data from an Employer-Sponsored Quitline.
Prev Chronic Dis. 2023 June 8;20:E46. doi: 10.5888/pcd20.220300. PMID: 37290008; PMCID: PMC10275326.

Numerous studies have supported the effectiveness and cost-effectiveness of quitlines for cigarette smoking cessation, but how effective they are for vaping cessation has not been established. Our secondary analysis examined quitline data on participants in employer-sponsored quitlines in the U.S. run by Optum, Inc to compare quit rates among callers who were exclusive vapers (n = 1,194) with those who were exclusive smokers (n = 22,845). We examined data from the time of quitline enrollment, January 2017, through October 2020. Before adjusting for differences in demographics, quitline treatment engagement, and unadjusted quit rates, the quit rates for vapers were significantly higher. However, after adjusting for demographic and treatment engagement variables, 6-month quit rates among vapers did not differ significantly from rates among smokers.
