My niece told my mom fuck you?

What to do when a child is out of control? My parents try to help her and they take her to school and buy her school stuff etc but she’s vaping, smoking weed and lord knows what else. She wears all black and smells really bad and won’t bathe. She won’t wash her hair either. Most recently she told my mom fuck you! What to do? And what is going on? She is 13. I get that she is going through puberty so don’t say that this is normal because it’s not.
