Definitely don't smoke anymore. It's still possible for it to be circulating through the placenta. Depending on your state and their regulations, any drug (including pot) that is found in your urine will be noted. When they test your babies first bowel movement (or blood sample) they will check for any signs of drugs. Depending on the state and protocol, you can have your baby taken away, either kept in the system or guardianship given to a family member until you complete drug courses.
I smoked marijuana until I went into labor I'm in Ohio I smoke marijuana helped with my morning sickness
I think if you stopped in December and haven't touched it since they won't be able to tell by the time the baby comes out. Cause I think it takes like a month to be undetectable in your system.
My sister in law smoked right up until she gave birth last year and they didn't say anything to her about it at the hospital about baby testing positive or anything. I think it was wise for you to stop when you did just don't smoke anymore to be on the safe side just in case your hospital does test you, I have read about some moms being investigated but I'm pretty sure you will be perfectly fine since they're becoming more lax about marijuana use in some states(idk where you live) and especially since you stopped when you did it should not be detectable in your body anymore.
