Awareness of the presence of nicotine in the JUUL Brand of e-cigarette among adolescents, young adults, and older adults in the United States

Figures & data

Figure 1. Proportion of adolescents, young adults and older adults who reported ever use, past 30-day any use, past 30-day frequent use, and current ownership of a JUUL e-cigarette. Note. Ns are unweighted; percentages are population-weighted. Key: Adol.: Adolescents (13–17 years); YA: Young Adults (18–24 years); OA: Older Adults (25–99 years).
