Smoking weed as a parent

I used to smoke weed before bed until I found out I was pregnant. My son is a year old now and I have been thinking about smoking again but I am nervous because I haven't in such a long time and I don't want to act or feel different around my son (not even if he's asleep and I'm about to go to bed). The only problem is that I have severe anxiety and it makes it hard for me to fall asleep at night, especially now that I have my baby to worry about. Just wondering what other moms/women think about smoking herb as a parent?
