Two Georgia State University School of Public Health professors, Dr. Scott Weaver, research associate professor, and Dr. Jidong Huang, associate professor, were co-authors on a study of e-cigarette product preferences among adult smokers.
In the study, the researchers used a discrete choice experiment (DCE) conducted August-October 2017 to examine electronic nicotine delivery systems (ENDS) product preferences in a national sample of adult smokers (N = 1154) who were also using ENDS or had not ruled out future use. Results of the study showed that among cigarette smokers who were not ENDS rejecters, 76 percent were daily smokers, 77 percent were ENDS ever users, 47 percent were current dual users of both ENDS and cigarettes, and 51 percent of the participants were randomized into the condition of seeing the incentive.
The study’s choice modeling results suggested that:
- smokers prefer cigarettes to ENDS or none of the products;
- higher ENDS refill prices significantly reduced the probability of choosing the product;
- an ENDS product that is less harmful to health than cigarettes, compared with no such information given (ie, left blank), was associated with a higher probability of choosing the ENDS product;
- compared with an ENDS product that is not effective in helping people quit, an ENDS product that is effective or with an unknown effectiveness was associated with a higher probability of choosing the product;
- compared with tobacco flavor, menthol flavor significantly reduced the probability of choosing ENDS; and
- fruit/candy/sweet/ other flavors, compared with a tobacco flavor, also significantly reduces the probability of choosing ENDS.
