I can’t stop smoking weed :(?

I can’t stop smoking weed, I live with family and they smoke in the house, even when I ask them to stop they won’t. I am unable to move out cause I’m 17 and enrolled in college full time, also working part time and I make like no money. I’ve been smoking like everyday for 3 years I know I’ve probably done lots of damage to my brain. I have had substance abuse problems in the past and ik this is a placeholder for harder drugs. Idk if people go to rehab for marijuana addiction but rehab also isn’t a option right now. Anyways thanks for reading all this mess, any tips would be greatly appreciated.
