Don't be fooled my sister smoked during her first pregnancy because of extreme all day and night sickness and her doctor knew. Needless to say child protective services took her daughter and took almost a year to get full custody back.

I doubt it. Smoking anything is bad for the baby's lungs and it's illegal 

Even where marijuana use is legal it is not legal to use while pregnant. If tested and positive, you can be charged with child neglect and abuse and most certainly face CPS charges. So I HIGHLY doubt a medical professional prescribed marijuana as medication. 

I have no friends who smoked weed and had healthy babies lol there was always something wrong.

I only smoked twice with my first pregnancy . I smoke now when I'm having really bad nausea or can't get comfy to sleep. Just don't use cigarillos cause of the Tobacco 

Smoking anything is bad, pregnant or not.

Yes. A few friends did, and they have perfectly healthy babies.

I've never heard of it being prescribed, but I have heard of people continuing to smoke while pregnant. I read a study about women who smoked marijuana during pregnancy and they tested the babies throughout a year after they were born and showed no defects or learning problems. Some babies of women who smoked seemed to even be more social. I think it's definitely something that should be looked more into, and every study on it should account for women also continuing to smoke cigarettes or drink, which several studies that claimed it caused birth defects didn't seem to account for.

People get prescribed marijuana for morning sickness and insomnia in some states. And as far as what I have read and heard it is Not smoking it, but eating. Someone got prescribed special suckers and goodies to eat in the morning to ease the sickness and I read about someone taking some thc oil (sublingual I think?) to help sleep at night. So who knows? Only the long term effects will tell what it truly does. I don't think it is worth the risk but I do think if used responsibly by women with a good sense of morality and self discipline it will be better than using chemical filled over the counter drugs. 

My sister inlaw gets medicinal marijuana(edible) for her pregnancy complications. She is on pregnancy number 7, she had miscarriages and stillbirths all different times, she is 24. She has alot of complications and her body has been preparing to push her baby out since her 16th week. She should be due end of July but she will be lucky to make it to spring. After this pregnancy she is getting her tubes tied to prevent any further health complications to her.
