I Want the Police to Arrest My Son Who Is a Drug Addict,and Offer Him Mandatory Rehab or Jail. How to Do It??

The drugs/alcohol are out of control. He drives/drunk or high and avoids getting caught. He dissappears for days. He never pays taxes. He uses the Emergency Room as a doctors office and never pays the bill. He refuses drug treatment voluntarily. I am at the end of my rope. I want to see him stopped, but not go to jail. I want to see him court ordered into an inpatient rehab center, where he can get some help. How can I alert the authorities, so they can find him drunk driving or in posession of drugs, and know that the judge will NOT put him in jail, but order mandatory rehab?? I’ll even pay for the rehab if it isn’t too expensive. But, I need the court order to make sure he stays for the entire period. If he doesn’t, then the judge can throw him in jail. Who do I contact at the state, county or township level to ASK for the Rehab sentence ahead of time??
My son is 25 y/o.
