Objective. To describe the profile and patterns of dual uses (n=954) and exclusive cigarette users (n=2 070) and determine the correlates of more frequent e-cigarette use among dual users and their reasons for e-cigarette use. Materials and methods. An online survey of Mexican adult smokers. Logistic models regressed dual-use (exclusive smoking vs. dual user) on sociodemographic, smoking varia­bles and substance use behaviors. We conducted censorial binomial models to estimate the correlates of frequency of e-cigarette use among dual users. Results. Dual users were younger had higher education (AOR=2.22) and higher levels of smoking dependence (AOR=1.31), preferred cigarettes with flavor capsules (AOR=1.58) and had recently attempted to quit smoking (AOR=1.38). Marijuana use and being daily smokers were correlates of higher frequency of use among dual users. Conclusion. Dual users had a higher risk profile than exclusive smokers, which was even more prominent in dual-users who used e-cigarettes frequently.
