Is there any way to contact drug addicts for compulsory detoxification?

Write to him. Some drug rehabilitation centers can call, that is, people inside can call outside, but only their relatives. You know that the other party can meet at the drug rehabilitation center later, but you should bring valid documents, such as ID card and marriage certificate. If you don't know which warehouse the other person is being held in, you can also go to the drug rehabilitation center to find out.
