Smoking weed while pregnant

I have a friend who is expecting (due in August) and she has been smoking weed for her entire pregnancy.

This is her second kid, and with her first I remember she quit the same weekend she found out she was pregnant.

But now for some reason she has a big “I don’t care” vibe. I did ask her a couple months back if she was going to quit and she said maybe.

I know it’s not me, not my body, not my baby, nothing like that. I’m just curious as to what other people think?

Is that dangerous? Or is it no big deal? Also this isn’t like a prescription this is entirely recreational
