For emancipation I believe he has to prove he can support himself. I don't think that is an option.
He is edging up to 18 where you have no legal rights at all. I had a daughter who used drugs in high school. She quit after we made her leave, but nothing we did while she was still here did any good. She was creative in contacting her drug buddies as we were also homeschooling her. She did not have access to social media because she used drugs up to twelve years ago, and that was before cell phones and social media took off. But she managed to sneak out her window at night and run the streets and to instant message (remember that?) some bad people.
They quit when they want to quit and don't feel bad that so far nothing worked. We have little power over defiant teens. Often they are told to leave at 18. Check your eviction laws.
Did you call the police when he got violent?
Do you have other children who have to see this behavior?
