Boyle, Richter, Helgertz (2019) Who is using and why: Prevalence and perceptions of using and not using electronic cigarettes in a statewide survey of adults Addictive behaviors reports 10() 100227


A statewide survey examined prevalence, reasons for using, discontinuing use, and not wanting to try e-cigarettes. Participants (n = 6052) were adult Minnesota residents. E-cigarette initiation and current use prevalence rates were calculated for demographic characteristics and smoking status. The percent of respondents endorsing a reason for trying e-cigarettes are reported overall and by smoking status. The percent of respondents endorsing each reason for discontinuing or not using e-cigarettes are reported for daily and occasional smokers. All descriptive analyses were weighted. To develop profiles of e-cigarette users, a latent class analysis (LCA) was undertaken. Overall, 20.7% of adults reported ever use and 4.6% were current users. Use varied notably by age and smoking status. Only 2.8% of never smokers were current e-cigarette users. Among young adults, 14.6% reported current use but most (70.0%) were never smokers. The reasons given for using e-cigarettes varied by smoking status. Curiosity was the top reason for all groups except recent former smokers, for whom cutting down or quitting other tobacco products was primary. Most smokers discontinuing e-cigarettes preferred cigarettes, and four-fifths of smokers who never tried e-cigarettes lacked interest. From the LCA four profiles were evident: young adult experimenters, curious adults, smokers trying to quit cigarettes, and dual users. Innovative higher nicotine content devices have sustained interest in e-cigarettes especially among young adults and smokers with a goal of cutting down or quitting smoking. Future regulations and communication should focus on reducing e-cigarette use among young adult nonsmokers. © 2019 The Authors.
