breastfeeding and smoking marijuana

I know there is going to be a lot of negative  comments but I'm just curious. I know some ppl smoke marijuana while pregnant to help with sickness and what not. I did up to my second trimester when my morning sickness stopped. I only took a hit twice a day, maybe 3 if I felt very very sick. But it was the only way I could eat or keep anything down. But once my morning sickness was gone, I stopped. So now my question is, just because I'm curious, is it bad to smoke weed while breastfeeding. I've googled it and it says it is bad, but when I googled smoking weed while pregnant there was positive and negative about it. But with the breastfeeding I'm only finding negative.
