Breast milk + THC

I experienced an infant loss at 39+1 on 10/26 and since I had him my breast have been engorged. I tried ice packs, cabbage, and hot showers to try and stop my milk flow because it’s a sad reminder of the baby I don’t have. I’ve been pumping and dumping about two medela bottles full on each breast every sitting.

I’ve been strongly considering donating milk. I think assisting other babies and mommies would help in my healing process. But since my loss I have used marijuana on occasion. Nothing heavily just a hit or two to ease my pain. Is there anywhere I am able to donate milk with THC or how long does marijuana stay in breast milk so I can donate?
