Anyone smoke or eat marijuana throughout their pregnancy?? what happened to your baby??

My friend swears her baby is "smarter" and more alert. My other friend who is 25 weeks still smokes too and I tell her I don't think it's healthy for the baby. She's going based on the other friend who smoked the whole time during her pregnancy saying that it's not going to do any harm to her baby. I'm looking for moms who smoked during their pregnancy (not tobacco, marijuana) and the baby didn't come out perfect like my other friends baby did. I think she just got lucky tbh.
