My cousin is a meth addict,she injects it in her veins,I don t have anything to do with her as she steals and lies ect.She has called me today though,saying she thinks someone has injected her with bleach,her arm has swollen up 5 times the size of the other one,it s black and hanging limp and she can t move it and has chest pains,and will not go to the hospital.Could this kill her
