help!!!should I be breastfeeding

EDIT!!!:::
Has anyone ever breastfed and smoked marijuana at the same time or while still potentially in their system? I smoked the other day (4times in one day), baby is almost 5 weeks old now, I have pumped milk to last for maybe a week at most. Will I be ok to breastfeed as long as I don't smoke anymore???
I want to know how long I should hold off on actually breastfeeding him??
Not looking for any hate pls ... haven't breastfed since I smoked. Pumping & dumping, and giving stored breastmilk through bottle
