Breast feeding question

*no bashing please*

I had my baby a little over a month ago and he's been in the NICU, I hit a really hard depression and instead of getting put on a pill I decided to smoke some weed to help with the depression and anxiety. (No, I didn't smoke when pregnant and it is legal to smoke in my state) my question is, if I wanted to start breast feeding, how long would I have to wait until the THC is no longer present in my breast milk?
