DO take away the source of the addiction and everything which might pull him back in.
DO
DO have a person in authority around. This person should be able and competent, not some moron.
DO give something back (or enable him) to replace the addiction. Preferably something he likes or complies with his goals in life.
DO give space for emotions, but...
DON'T allow his emotions to control your (re)actions.
DO be honest (100% needed here).
DO take time for your own emotions. You're going to shed some tears, trust me on this.
DO establish structure in his life. Shove it down his throat if needed, however...
DON'T become abusive (in any way).
DON'T allow yourself to be abused.
DO remain calm.
DO try to figure out what created the space for the addiction to occur in the first place and send him to therapy, if needed (make sure he goes).
DO be patient. It takes time to get rid of addictions.
DO be observant. In the beginning he'll do anything to get to his addiction.
DO have a social worker or (even better) a therapist available.
If the person starts shouting, his eyes dilate, his face becomes red and he starts clenching his fists, lower your voice to a level that he's got to concentrate to hear you. Anger and concentration cannot occur together. Doing this might very well spare you several bruises. Making him laugh will also help.
