Frequency of self-reported exposure to secondhand smoke and secondhand aerosol from e-cigarettes in public during the past 30 days among US middle and high school students reporting any exposure, National Youth Tobacco Survey, 2017. Left: The frequency of secondhand smoke (SHS) exposure is calculated among respondents who reported being exposed to SHS (unweighted, n = 8,273). Right: The frequency of secondhand aerosol (SHA) exposure is calculated among respondents who reported being exposed to SHA (unweighted, n = 4,138). Percentages are based on weighted data.
