ABSTRACT The legalization of marijuana is increasing in the United States. With more dispensaries opening, it is essential to look at these businesses' impacts on neighborhood crime rates. Alcohol outlets are known as crime attractors/crime generators, and their presence in a neighborhood is also significant to look at when investigating violent crime rates. It is crucial then to take both marijuana and alcohol outlets together to determine the effects these facilities have on aggravated assault and robbery in a neighborhood. To assess the impact of marijuana outlets, on-premises alcohol outlets, and off-premises alcohol outlets in Los Angeles, California, on aggravated assaults and robberies, this thesis uses Los Angeles business, crime, and census data. The study addresses the following research questions: (1) Does an additional marijuana outlet in a neighborhood increase aggravated assaults and robberies? (2) Does the presence of on- and off-premises alcohol outlets increase aggravated assault and robbery? (3) Does the presence of multiple types of risky businesses increase violent crime? The current study finds an increase in aggravated assaults and robberies when marijuana outlets and on- and off-premises outlets are located in a neighborhood. The only non-significant finding is when all three outlet types were present; marijuana outlets are the only outlet type not associated with an increase in robbery. These findings suggest that limits should be placed on the number of risky retailers in a neighborhood and provides policy implications directed toward reducing violent crime near marijuana and alcohol outlets.
