In this analysis, discordant report was defined as reporting of vaping of cannabis via vaporizer and then not reporting vaping of cannabis later on the survey. Missing data were eliminated listwise in bivariable tests comparing discord vs. no discord. The multivariable model, however, utilized imputed data so no data were missing. MSA = metropolitan statistical area; aPR = adjusted prevalence ratio; CI: confidence interval.
