Trends and variations in admissions for cannabis use disorder among pregnant women in United States

This research highlights two decades of trends in treatment admissions for cannabis use disorder (CUD) among pregnant women in the U.S. Using national treatment episode data from 2000 to 2021, the study shows that admissions for CUD have fluctuated significantly, with notable differences by age and race/ethnicity. While admissions peaked in 2018, they declined in recent years—possibly reflecting shifts in public attitudes, access to treatment, and the normalization of cannabis use. The study also underscores the high prevalence of co-substance use, suggesting that cannabis use during pregnancy often occurs within a broader pattern of polysubstance use.
