Everyone here is trying to tell you, as kindly but firmly as we can, that if nothing changes, nothing changes. You may not be able to control what she does, 24/7. BUT you don't have to support it, either. You don't have to give her money, a roof over her head, food on the table. You provide those things for a child who is working or going to school, not one who is partying on your dime. She doesn't CARE what you expect of her. Not enough to change her behavior.
Boundaries--get some.
