Weed during pregnancy

Ok.! So I'm having an argument with my man telling him that weed and cigs are bad for you while pregnancy. Suddenly he's like weed is better than cigs. I'm like are you serious?
Maybe it's my hormones going off but I'm so completely against any drug. And yes weed is a drug! It's a narcotic. 
Ugh! But he's all saying weed is better than cigs!
I want to know what you guys think
