E-Cigarettes in Baltimore Alcohol Outlets: Geographic and Demographic Correlates of Availability.

There is limited research on e-cigarette availability despite increased use. E-cigarette availability within Baltimore alcohol outlets was analyzed for disparities among residential neighborhoods. Data were obtained via field surveys of alcohol outlets, and then spatially merged with sociodemographic data; 18.8% of alcohol outlets had any e-cigarette availability. Regression models showed greater odds ratios for e-cigarette availability when cigarettes, cigars, or hookah paraphernalia were sold, and lower odds ratios when alcohol outlets had an on-site consumption license. Outlets with e-cigarette availability were in predominantly lower-income, nonwhite neighborhoods. It is important to assess exposure of another potentially damaging substance among perpetually disadvantaged populations.
