Investigating how people use both combustible and electronic cigarettes to help quit smoking

Official title: Dual use of combustible and electronic cigarettes: A fine-grained naturalistic cohort study to investigate dynamic use patterns and trajectories that lead to smoking cessation

Funded at Medical University of South Carolina · NIH-11124145 · Data updated 2026-11-12

This study is looking at people who smoke regular cigarettes and use e-cigarettes to see how they switch between the two and if it helps them quit smoking for good, with the goal of finding better ways to support those trying to stop.

Who could benefit from this research

Could help

Ideal candidates for this research are adults aged 21 and older who currently use both combustible and electronic cigarettes.

Less likely to help

Patients who exclusively use either combustible cigarettes or electronic cigarettes without dual use may not benefit from this research.

What this research studies

This research examines the patterns and behaviors of individuals who use both combustible cigarettes and electronic cigarettes. By following a cohort of participants over time, the study aims to understand how these dual users transition between products and whether this affects their ability to quit smoking altogether. The research will collect detailed data on daily usage patterns to identify factors that contribute to successful cessation or continued use. This information could help inform treatment strategies and public health policies regarding tobacco use.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for helping individuals quit smoking by understanding the dynamics of dual tobacco product use.

How similar studies have gone: While there have been studies on tobacco use, this research focuses specifically on the dual use of combustible and electronic cigarettes, making it a novel approach.
