Background and Objectives E‐cigarette use is associated with concurrent use of combustible cigarettes among adults and may increase the risk of future combustible cigarette use in adolescents and young adults. Detrimental effects of combustible cigarette use on sleep health are well documented, but little is known about the additive effects of concurrent e‐cigarette use. The current study examined the main and interactive effects of daily nicotine product frequency on various components of sleep health. Methods Two hundred and twenty‐seven dual‐product users (54.2% female, M age = 36.89, SD = 10.17) completed questionnaires regarding demographic information, average number of cigarettes smoked per day, average number of times e‐cigarettes used per day, and sleep health. Results Combustible cigarette frequency uniquely predicted shorter sleep duration, whereas e‐cigarette frequency uniquely predicted increased daytime dysfunction due to sleepiness. Further, there was an interactive effect of combustible and electronic cigarettes on the use of sleeping medications. Discussion and Conclusions Findings may suggest differential adverse effects on sleep, depending on the type of nicotine product used, and highlight potential intervention targets for users. Future work should examine these associations prospectively and/or use objective measurements of sleep and nicotine use to further elucidate the nature of these relationships. Scientific Significance This is the first study to explore the main and interactive effects of dual‐product use on various dimensions of subjective sleep quality. This is important to investigate, given that dual nicotine users are at greater risk for physical health problems as well as the adverse effects of nicotine on sleep health.
