most sources will tell you marijuana is harmless to the baby...i look at it this way, itd be better if my gf could eat and smoke pot than not smoke pot and barely eat anything. (my gf is 8 months pregnant) She has stopped until she has the baby though so that way weed doesnt come up when they test the baby so we dont get our son taken away, so watch out for that too, she'll have to stop a few months before roughly, dont really remember, look that up though if she does decide to use weed during pregnancy, and make sure she stays away from that wine
