This session examines the relationship between cannabis legalization in New York City and trends in cannabis-related mental health concerns, with particular attention to psychosis and racial and socioeconomic disparities. Drawing on longitudinal public health data from the pre- and post-legalization periods, the presentation explores changes in cannabis-related emergency department utilization, patterns of psychosis, and populations experiencing disproportionate risk. Particular attention is given to Black, Latino, low-income, and younger New Yorkers, as well as the potential influence of increased cannabis accessibility and high-potency products. Findings are considered within the broader context of social determinants of health, health equity, and evolving cannabis policy. The session will discuss implications for social workers, behavioral health professionals, educators, and policymakers, emphasizing the importance of prevention, early identification of cannabis-related psychiatric symptoms, culturally responsive education, harm reduction, and equitable access to mental health services as the legal cannabis market continues to evolve.
