Our expert says:
I wish people would lose the word "confront" as it is so rarely a useful thing to do. But what you are describing is someone either seriously sick in some way, or deeply affected by the use of large quantities of some drug or drugs, and likely to get himself into serious trouble. But unless he is either picked up by the police in a public place or for doing something wrong, and they might choose to get a police surgeon to examine him ; or unless he collapses in a public place and is taken to a hospital for assessment, ; he would be hard to help unless and untill he recognizes that he is in a serious state and seeks help voluntarily. If he has family, you could contact them, and they might have found ways to help him previously ; and if he has a GP, you could inform the doctor that he may well be a danger to himself in this state. There are ways that someone could be compulsorily admitted for assessment and treatment, but this would need the involvement of a doctor who knows him and of his family.
