Weed and breastfeeding

Morganalysss

I was wondering if anyone has smoked once or twice we’ll they were breastfeeding? I smoke up until I was 18 weeks pregnant and they always said he looked perfect on the scans, he came one his due date naturally after my water broke. I only stopped smoking because I had heard that they drug test every baby and mom before leaving the hospital. I live in a non legal state and I was just wondering if I would be okay to smoke a few times when I’m having horrible knee and back pain. Obviously not going to smoke around my son. Please don’t start a bunch of hate or drama on this I’m just wondering if it would be better to smoke once in a while and still breastfeed or if I should switch to formula. He’s 3 months and 15 pounds
