I use medical marijuana to treat my hyperemesis daily. One of my midwives was concerned and stated that I should use zofran instead.. I don't agree with some known to cause birth defects. I have used marijuana edibles with my last two pregnancies and I have to very happy and healthy children. I do not agree with smoking it due to it causing lack of oxygen to the placenta but I feel it's my choice to use which medication I feel works best and is safest for myself and daughter.
