Predictors of Dual E-Cigarette and Cigarette Use

Area of Science:

• Public Health
• Epidemiology
• Behavioral Science

Background:

• E-cigarette use (vaping) has rapidly increased, particularly among young adults.
• Understanding the prevalence and predictors of dual use (using both e-cigarettes and traditional cigarettes) is crucial for public health strategies.

Purpose of the Study:

• To compare the prevalence of e-cigarette and traditional cigarette use.
• To identify factors predicting dual use among adults.

Main Methods:

• A countywide random digit dial telephone health survey was conducted from January 2018 to March 2019.
• Data from 6966 adult participants were analyzed using bivariate analyses and multivariable logistic regression.

Main Results:

• Young adults (18-24) exhibited the highest prevalence of exclusive e-cigarette use (11.5%) and significant dual use (3.9%).
• Males were more likely than females to engage in e-cigarette use, traditional cigarette use, and dual use.
• Approximately half of e-cigarette or dual users reported concurrent marijuana use in the past 30 days.

Conclusions:

• E-cigarette uptake among young adults is a significant concern due to its potential to lead to dual use.
• Findings underscore the need for further research and targeted public health interventions to address evolving substance use patterns.
