Abstract
Purpose This study compares access to flavoured JUUL and other e-cigarettes from retail, online and social sources among underage and young adult e-cigarette users who live in California jurisdictions that restrict sales of flavoured tobacco with the rest of the state. Methods An online survey used social media advertisements to recruit participants (n=3075, ages 15–29) who lived in one of nine jurisdictions that restrict sales (n=1539) or in the rest of state, and oversampled flavoured tobacco users. Focusing on past-month e-cigarette users (n=908), multilevel models tested whether access to flavoured JUUL and other e-cigarettes from retail, online and social sources differed by local law (yes/no) and age group (15–20 or older), controlling for other individual characteristics. Results The percent of underage users who obtained flavoured JUUL and other e-cigarettes in the past month was 33.6% and 31.2% from retail, 11.6% and 12.7% online, and 76.0% and 70.9% from social sources, respectively. Compared with underage and young adult users in the rest of California, those in localities that restrict the sales of flavoured tobacco were less likely to obtain flavoured JUUL from retail sources (Adjusted OR=0.54, 95% CI 0.36 to 0.80), but more likely to obtain it from social sources (Adjusted OR=1.55, 95% CI 1.02 to 2.35). The same pattern was observed for other brands of flavoured e-cigarettes. Conclusion Although local laws may reduce access to flavoured e-cigarettes from retail sources, more comprehensive state or federal restrictions are recommended to close the loopholes for online sources. Dedicated efforts to curtail access from social sources are needed.
