Sources of Awareness of JUUL E-cigarettes in 2 Surveys of Adults in the United States.

Since their introduction in 2015, JUUL e-cigarettes have gained >60% of the United States (US) 2018 retail market share among branded e-cigarette companies. The sources through which consumers learn about JUUL e-cigarettes is not known. We assessed the sources of awareness about JUUL through 2 cross-sectional surveys of US adults (Survey 1: 502 18-24 year-olds; Survey 2: 803 smokers age 18+). Primary measures were awareness of JUUL and sources through which participants learned about JUUL. Awareness of JUUL was greater among smokers and younger adults (age <30). Common sources of awareness were advertisements, news, and word-of-mouth. This study is the first to identify sources through which never, non-current ever, and current smokers learned about JUUL e-cigarettes. Regulatory efforts and educational interventions may opt to focus on these channels.
