My mom smokes pot...?

I'm already prepared for the ignorant answers of "get over it and smoke with her" but I refuse. I will never be okay with it. I've confronted her about it and she tells me to just get over it. She's started growing it, she says only for her to smoke, but it ticks me off that she would do something so illegal and selfish with me living there still. I have an opportunity to move out early. I'm going into my senior year at high school, I would still go to school and what not, so is it a good idea? I don't know what to do and I'm tired of being the bad guy.
