As one who works every day with pregnant mothers as well as neonates, it is listed on their charts what drugs they do, and what they don't do.

I have found no difference with pot babies versus regular babies, even when they come back for their 6 month, 1 year, and 2 year check-ups. The OBGYN I work with doesn't have any qualms against eating cannabis while you're preggers, because it essentially affects the baby as much as it does you.

I wouldn't smoke in the first trimester though, just in case. But after that, it's all good as long as you don't overdo it.
