Well smoking cigerettes and pot will most likely have the baby be underweight especially since cigerettes have something in it that makes people not have an appetite and you are doubling up on how much carbon monoxide you are putting in your body.

But coming from the doctor if you smoke alot of weed even before you found out you were pregnant, They said that you cannot quit cold turkey because it will put a shock to the baby's system and cause more problems than continuing to smoke. They said they are more concerned with the harder drugs since the only problem would be the low oxygen level from the carbon monoxide.

As for the drug testing, in the state of Iowa it's if you are on file at DHS for having problems with previous kids because it gives them probable cause.

I know many people who only smoked weed while they were pregnant and had no problems but one person did have the baby a month early because it developed everything early and its a healthy baby girl.

This website (Melanie Dreher, Jamaican Pregnancy Study) that shows a research done in Jamaca :rastasmoke: on pregnant women and how their children developed over time after the pregnancy. They found that there was no difference between the children of a user and of a non-user..

If you do continue to smoke be careful on who you are getting it from, where it's coming from etc. because you could run the chance of having problems if it is laced with another drug or chemical and if you want to quit try to do it slowly and not cold turkey.
