The objective of the study was to evaluate the transfer of delta-9-tetrahydrocannabinol and its metabolites into human breast milk after maternal inhalation of 0.1 g cannabis containing 23.18% delta-9-tetrahydrocannabinol. (In clear language – what’s the effect of smoking pot on your breast milk?)

This study documents inhaled delta-9-tetrahydrocannabinol transfer into the mother’s breast milk. Low concentrations of delta-9-tetrahydrocannabinol were detected. The long-term neurobehavioral effect of exposure to delta-9-tetrahydrocannabinol on the developing brain is unclear. Mothers should be cautious using cannabis during pregnancy and breastfeeding.

In short – if you smoke pot, this study indicates it will get into your breast milk.
