I'm a nursing tech on a pediatrics/labor and delivery floor. I have seen many babies come and go over the past 5 years... Some of the mothers who were tested for drugs ended up having babies born with cannabis in their system. By protocol, we were required to treat them for withdrawal, though from both my personal observations, as well as the plethora of nurses and OBGYNs on my unit, it's pretty much a joke. The only infant who did have signs of withdrawal, who tested positive for THC was also suffering opiate withdrawal.

Generally in Maryland, unless they have a reason to test the baby/mom for drug use, they won't. The babies with THC in their systems generally require a very short social work consult, but nothing of consequence.

I know this is purely anecdotal, but my best friend's mother is a very intelligent woman- one of the most respected arachnologists in the country! She also smokes pot. And lots of it. She admitted to smoking when pregnant, for both children. My friend is absolutely brilliant, and a wonderful person, as is her brother.

Good call for those of you who recognize more harm in the combustion of the plant material as more of a harmful thing than the THC and CBNs. Cannabinoids are actually produced by the mother when breastfeeding- this encourages the infant to keep drinking the nutritious milk, though I wouldn't necessarily smoke and then immediately breastfeed, the chemicals are passed to the baby.

I'd think vaporizers, brownies, tinctures, etc. would be best during pregnancy, though.
