Weighted multivariable logistic regressions identified independent associations between relative and absolute e-cigarette and cigarette harm perceptions at baseline and continued smoking, dual use, complete switching, and quit intention at follow-up, stratified by age (young adults [YAs] 18\u201324, middle-aged adults [MAs] 25\u201344, and older adults [OAs] \u226545) among U.S. adults who smoke (n\u2005=\u20058231).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Perceiving e-cigarettes as less harmful than cigarettes was associated with higher odds of complete switching from cigarettes to e-cigarettes (adjusted odds ratio [aOR] overall: 1.52; MAs: 1.68). Perceiving e-cigarettes as very\/extremely harmful was associated with lower odds of dual use (overall aOR: 0.75; MAs: 0.72) and higher odds of quit intention (aOR OAs: 1.34). Perceiving cigarettes as very\/extremely harmful was associated with lower odds of continued smoking (overall aOR: 0.69; MAs: 0.76; OAs: 0.53), and higher odds of complete switching (overall aOR: 1.65; MAs: 1.86) and quit intention (overall aOR: 1.58; MAs: 1.42; OAs: 1.80).

This study adds that low relative harm perceptions of e-cigarettes can promote complete switching among MAs who smoke. High absolute harm perceptions of e-cigarettes may deter dual use among MAs. Additionally, high absolute harm perceptions of cigarettes may reduce smoking and increase cigarette smoking quit intentions among MAs and OAs. Future research is needed to understand the beliefs that support harm perceptions among different age groups, why their effects differ by age, and what factors influence YAs\u2019 tobacco use behaviors.<\/jats:p>\n
