Breastfeeding & Marijuana

Colorado and Washington became the first states to fully legalize the recreational use of marijuana back in 2012. Since then, many states have followed. Although marijuana is usually a non-harmful drug, researchers do not know the effect THC can have on a fetus during the prenatal period or on infants during breastfeeding. As a start, researchers at Children’s Hospital Colorado set out to understand how much THC is excreted in breast milk and for how long.
