A drug abuser who does not want to quit or even acknowledge that there is a problem.

The most important factor in this scenario is to make the abuse admit that they've got problems. One of the ways that I thought of to make the abuser admit he has problems is to test him physically and psychologically. It might be cruel but in order to test the abuser physically, I think I should stop him from taking drugs for a while and see the reactions. Then I record the reaction and show it to the abuser when the abuser is in a good psychological state because sometimes the abuser could be out of their minds and don't know what I am talking about. Then maybe the abuser will realize that he has problems both psychologically and physically because he will be able to see him craving for more drugs and see himself tremble and shake when he is not given doses of drugs. Another way might be doing a drug test on him but I don't think that would give the same impact as seeing himself suffer, craving for drugs. Then when the abuser realizes that he's got problems, the next most important thing is the commitment of the abuser to stop taking drugs. Of course there should be a companian besibe to help and guide him through hardships and eventaully to freedom.
