ABSTRACT
Cannabis legalization and use are increasing rapidly in the United States while research on the potential harms and benefits of this increased access lags behind. While there are many avenues of research involving the implications of increasing cannabis use that should and are being pursued in a variety of disciplines, the fields of Social and Health Psychology are uniquely poised to address research questions surrounding individual and social factors implicated by cannabis use. In this review, we explore how research into cannabis harms and benefits intersects with key social and health psychological phenomena including stigma, identity, prejudice, health behavior promotion, and intimate relationships. We argue that social and health psychologists can bring a theoretically rich and empirically rigorous lens to a field that is evolving rapidly, and in doing so, help shape a more equitable and evidence-informed future for cannabis research and policy.
