So I was talking to my midwife about how I've been having crazy vivid dreams and horrible nightmares all the time and I told her I used to smoke before bed before I knew I was pregnant. She said it's fine as long as I'm not smoking over 3g a day it's safe to have a puff before bed (Im using homegrown stuff without chemicals) so I can stop the nightmares. I was wondering what yall think should I do it? My main concern is I just don't want to hurt my baby or cause damage :( need reassurance or advice please.

My normal doctor said it has the same effects as alcohol. But my midwife says there is no studies to prove that and she said it should be fine.
