I stopped smoking weed and yes it was hard bc I seriously think it is much safer then cigarettes but when it came to it I didn't want the hospital to place my child in foster care so that there motivated me to stay clean.
Not only is the action of smoking itself is detrimental to the health of the baby, but we do not know how cannabis intake can affect the developing brain. As you mentioned, you are using it for nausea, you may have hyperemesis gravidarum, a condition that causes excessive nausea and vomiting during early stages of pregnancy. There are other medications that are proven safer during pregnancy that are effective for nausea that your OB can prescribe for you. If your OB is aware of your issue they will be happy to address it. However you did not say you are feeling sick and are using it only to increase your appetite. Your appetite will increase in a few weeks even if you do not smoke mj and the baby will not be harmed as long as you do not intentionally starve yourself.
You want to eat right and stay away from all unneeded drugs and alcohol while you are pregnant and nursing or mothering young children. Please take good care of yourself and that way you can be sure you are taking the best care of your child!
