OBJECTIVE: To determine whether maternal cannabis use disorder is associated with infant hospitalization or death in the first year of life.

METHODS: We queried an administrative birth cohort derived from the hospital discharge database maintained by the California Office of Statewide Health Planning and Development and linked with vital statistics files. We included singleton, live-birth deliveries between 2011 and 2018. Pregnancies with cannabis use disorder were classified from International Classification of Disease codes. Outcomes included infant emergency department visits and hospital admissions identified from health records, and infant deaths identified from death records. Models were adjusted for sociodemographic variables, psychiatric comorbidities and other substance use disorders.

RESULTS: There were 34,544 births (1.0 %) with a cannabis use disorder diagnosis in pregnancy, with increasing prevalence over the study period. The incidence of infant death in the first year of life was greater among those with a maternal cannabis use disorder diagnosis than those without. When examining specific causes of death, the increased risk estimates were attributable to perinatal conditions and sudden unexpected infant death. After adjustment, there was no increased risk of infant hospitalizations or emergency department visits.

CONCLUSIONS: These findings warrant further investigation into the underlying mechanisms of maternal prenatal CUD on infant outcomes, and add to a rapidly expanding body of literature supporting the need for effective treatment options for pregnant individuals with cannabis use disorders.
