Research on drug markets indicates that they are not randomly distributed. Instead they are concentrated around specific types of places. Theoretical and empirical literature implicates routine activities and social disorganization processes in this distribution. In the current study, we examine whether, consistent with these theories, drug markets are particularly likely to form near schools. This research contributes to our understanding of adolescent drug use patterns by assessing some of the place and neighborhood-level mechanisms that help explain how schools facilitate access to illicit drugs. Using data from Albuquerque, New Mexico, we find that neighborhoods with middle schools and high schools experience more drug crime than neighborhoods without middle or high schools. Moreover, the relationship between school presence and drug crime is strongest during the hours directly before, during, and after school. Theoretical and policy implications are discussed.
