Introduction:
Youth use of electronic cigarettes (e-cigarettes) is rising globally and is associated with health harms. Flavor descriptions on e-liquid packaging may contribute to the appeal of e-cigarettes among youth. This study compared subjective ratings of e-liquid packaging flavor descriptions among nonsmoking and non-vaping UK adolescents.
Aims And Methods:
This was an online observational study in a UK sample of nonsmoking and non-vaping adolescents aged 11-17 years. The primary analyses compared flavored versus unflavored descriptions and the secondary analyses compared sweet flavor versus fruit flavor descriptions. Outcomes were packaging appraisal, packaging receptivity, perceived harm, and perceived audience.
Results:
The survey was completed by 120 participants (74% female). Packaging appraisal ratings were higher for e-liquids with flavored descriptions than unflavored descriptions (mean difference 5.9, 95% CI: 4.2 to 7.6, p < .001). Similarly, packaging receptivity ratings were higher for e-liquids with flavored descriptions than unflavored descriptions (mean difference 4.2, 95% CI: 2.8 to 5.6, p < .001). Participants also perceived e-liquids with flavored (vs. unflavored) descriptions as less "grown-up" (mean difference -5.2, 95% CI: -7.3 to -3.1, p < .001). However, ratings of perceived harm were similar for flavored and unflavored descriptions (mean difference -1.0, 95% CI: -2.6 to .5, p = .189).
Conclusions:
Although this study found differences in subjective ratings of e-liquids with flavored and unflavored descriptions, nonsmoking and non-vaping UK adolescents generally had low appraisal and receptivity for e-liquids and they perceived them as being "grown-up" and harmful.
Implications:
Youth use of electronic cigarettes (e-cigarettes) is increasing globally, leading to concerns about health harms. This study compared adolescents' ratings of e-liquids with flavored versus unflavored descriptions and e-liquids with sweet flavor versus fruit flavor descriptions. This study adds to previous studies that have compared adolescents' ratings of e-liquids with tobacco flavor versus non-tobacco flavor descriptions. Although packaging appraisal and receptivity ratings were higher (more positive) for e-liquids with flavored versus unflavored descriptions, overall, adolescents who do not smoke or vape had low appraisal and receptivity for e-liquids, and they perceived them as being "grown-up" and harmful.
