During breastfeeding, it's important to know that breast milk can contain THC for up to six days after use. This THC can affect brain development in newborns and cause hyperactivity, poor cognitive function and other long-term consequences. Cannabis use is 100% unsafe during pregnancy. It can cause complications similar to those caused by smoking, such as premature birth and congenital disabilities.
Many mothers who used cannabis before pregnancy may wonder if they can use it again while breastfeeding their baby. The use of marijuana while breastfeeding also carries the risk of harming the baby.
