My sister is living with my parents and doing drugs. If she were younger, they would force her into rehab, but she is an adult and she can only be forced into rehab by a judge now. Is there a way to get the authorities involved without her having to commit a more heinous crime first? Also, if authorities did find drugs in my parents' house, would they be held accountable for the actions of their adult daughter? She was previously arrested for driving while under the influence of marijuana, but was not convicted. She also has a history of meth use. Her behavior is violent, and her family does not feel safe around her. Rehabilitation would be best, but an intervention would not be successful. Her behavior has become bad enough that legal steps will need to be taken to get her help.
