Off-Premise Alcohol Outlets and Substance Use in Young and Emerging Adults.

This investigation examined the association between alcohol outlets and substance use during young adulthood in Baltimore, MD. Geospatial methods were used to determine the number of outlets within walking distance of the participant's home and distance to nearest outlet. Logistic regression models found that distance to the nearest alcohol outlet was associated with past year marijuana use after adjusting for community disadvantage and sociodemographic characteristics (OR = 0.77, p = .03); specifically, as distance to the nearest outlet increased the likelihood of marijuana use decreased. Findings suggest that distance to the nearest alcohol outlet was a better predictor of marijuana use than the density of alcohol outlets.
