What happens if i smoke weed while breastfeeding

My daughter is 2 weeks if that matters.

Edit: jesus christ I havent considered smoking weed while breastfeeding. I asked this question to show to my boyfriend to prove to him that its best for me to wait until im done breastfeeding to start smoking again because he has tried to convince me to smoke with him. Theres no need to be judgmental ass bitches and make assumptions.
