Sending me to rehab??

My mom found out that I smoke and she really thinks I’m a crack head or something. I’m 24 and I live with her while working two jobs and I go to college (I graduate in October btw). She said in order for me to live in her house I’m going to have to go to rehab because apparently I’m a dope fein. Meanwhile, she allows my underage sister to drink alcohol away at college. I’m so over this. I have to move out.
