Toward a “Post-Legalization” Criminology for Cannabis: A Brief Review and Suggested Agenda for Research Priorities

Cannabis control policies in a few countries have recently shifted from criminal prohibition-based regimes to legalization of use and supply. While cannabis’ newly emerging status of legality may suggest a coming “end” for criminology-based interest in the drug, these fundamental changes rather open a window to a new set of criminological research issues and questions, mostly focusing on cannabis use and related behaviors, and their relation to crime and justice. Based on a joint, personal record of several decades of criminological research on cannabis, we briefly review the rationale for five fundamental topics and issues of cannabis-related research associated with legalization. These include: 1) the deterrent effect of prohibition; 2) illicit production, markets and supply in a legalization regime; 3) use enforcement; 4) cannabis-impaired driving; 5) cannabis and crime. This constitutes an—albeit subjectively selective—“post-legalization” research agenda for a cannabis-focused criminology. Other possible areas of research focus or interest within fundamentally different paradigms of criminology (e.g., “critical criminology”) are identified and encouraged for development. Overall, the proposed research agenda for a post-legalization cannabis criminology should both contribute discipline-specific knowledge to improved cannabis-related public health and safety as well as allow for important debate and development in this evolving and important research field while entering a new (“post-legalization”) era.
