INTRODUCTION AND AIMS: Little is known about the spatial distribution of medical marijuana dispensaries, particularly whether or not sites are disproportionately located in minority or communities with younger populations. This paper will assess if there is a relationship between medical marijuana dispensaries and neighbourhood characteristics. DESIGN AND METHODS: This study used an ecological, cross-sectional design of 1000 census tracts from Los Angeles city in 2012 to explore the relationship between neighbourhood sociodemographics, structural features of neighbourhoods and density of medical marijuana dispensaries. Locations of dispensaries were obtained through a premise survey of all listed dispensaries. Data on neighbourhood characteristics were obtained from Geolytics. The study used Bayesian conditionally autoregressive models that include controls for spatial heterogeneity to analyse the data.

RESULTS: Findings show that dispensaries are located in areas that allow for commercial establishments.

RESULTS indicate a positive relationship between dispensaries and percent commercially zoned, areas with highway ramp access, density of on- and off-premise alcohol outlets and percent Hispanic residents.

DISCUSSION AND CONCLUSIONS: In sum, the findings suggest that, likely because of zoning regulations, dispensaries were located in primarily commercially zoned areas with greater road access (as measured by the presence of highway ramps). Given that areas with higher densities of dispensaries also have higher densities of alcohol outlets, future work should examine how this co-location affects neighbourhood problems such as crime and violence.
