Quit Attempts and Plans among Users of Conventional Cigarette, e-cigarette, and Heated Tobacco Product

Background: This study examined quit attempts and quit plans for combustible cigarettes (CC), electronic cigarettes (EC), and heated tobacco products (HTP) among Korean adults, according to patterns of tobacco-product use.Methods: A total of 8,000 adults (4,000 men and 4,000 women) aged 20-69 were surveyed using online panels.Quit attempts were defined as any attempt to stop using CC, EC, or HTP within the past 12 months, and quit plans were defined as intentions to stop each product within the next 6 months.Logistic regression analysis was performed to assess differences in quit attempts and quit plans according to patterns of tobacco product use.Results: After adjusting for age, gender, and socioeconomic status, CC-EC dual users and triple users had approximately 65% lower odds of attempting to quit CC compared with exclusive CC users.Among EC-HTP dual users, EC quit attempts were 35% lower than in exclusive EC users.CC-HTP dual users had 64% lower odds of attempting to quit HTPs, and EC-HTP dual users had 76% lower odds compared with exclusive HTP users.Regarding quit plans, CC-EC dual users had 32% lower odds of planning to quit CC, and triple users had about 50% lower odds.CC-HTP dual users had 70% lower odds of planning to quit HTPs, and EC-HTP dual users had 60% lower odds.Conclusion: Quit attempts and quit plans were consistently lower among poly users than among exclusive users.Considering the potential harm associated with ECs and HTPs, targeted, evidence-based cessation strategies are needed.
