Can CPS Take Away A Child If The Mom Is Breastfeeding?

My cousin has continued to party and abuse drugs. She leaves her daughter with complete strangers! They live in a trap house. She sells drugs. Has drug dealers around her baby. I came to check up on her and her baby was on the floor and she was passed out on the couch. I told her if she doesn't get it together I'm gonna have to report her to cps and she just said "Do it! I'm breastfeeding so they can't take my kid away". Is that true? Would it really be a waste of time to report her?
