Cannabis Use During Pregnancy Affects Breastfeeding Decisions

United States (10 states)Fri Sep 18 2026
Researchers explored how advice about cannabis impacts a mother's choice to breastfeed her baby. This study covered data collected between 2017 and 2021 from ten states that participate in the Pregnancy Risk Assessment Monitoring System. The team narrowed their focus to mothers who reported using cannabis during pregnancy. Key patterns emerged linking cannabis use timing, perceived safety, and clinical guidance to breastfeeding decisions.

Women who used cannabis exclusively after childbirth showed the highest breastfeeding rates. Nearly ninety percent of this group chose to nurse. In contrast, mothers who used cannabis both before and after delivery had much lower rates, around seventy-one percent. A striking difference appeared when considering perceived safety. Mothers advised against cannabis while nursing had lower breastfeeding success—about eighty-one percent—compared to ninety-four percent for those who received no such warning.

These results stress the value of direct counselor conversations about substance use during pregnancy. Healthcare professionals should provide clear, honest guidance about cannabis risks. Promoting breastfeeding remains the strongest recommendation for infant health. Future research could explore better ways to communicate these messages effectively.
