CBD in breast milk: new study to measure risks for nursing infants
NCT ID NCT06589258
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how much CBD (a legal substance found in cannabis) passes from a mother into her breast milk and whether it can be found in her baby's urine. Researchers will measure CBD levels in the blood and milk of 60 breastfeeding mothers who use CBD. The goal is to understand the potential dose a baby might receive and any biological effects.
