Users of both electronic nicotine delivery systems (ENDS) and cigarettes may be more intent on quitting tobacco, but that intention seems to drop off among less educated smokers, according to a study by Georgia State University researchers published in the journal Addictive Behaviors.

Through a survey of more than 1,200 smokers, researchers found those who did not have college degrees were less likely to use ENDS in addition to smoking regular cigarettes. But smokers who did use ENDS, such as e-cigarettes, were more likely to have attempted to quit in the past year, according to the survey data.

“Among dual users, having a college degree was associated with high intention to quit smoking and attempting to quit in the past year,” said Michael Eriksen, professor and dean of the School of Public Health at Georgia State and an author of the study. “This study highlights patterns in ENDS use that may increase the socioeconomic gap in smoking prevalence.”
