Please tell me what should i do if my father has a drug addiction?

Get guidance: You can do nothing to end your Dad's addiction. It may have little effect on his behavior, or it may destroy his ability to be decent, effectively, or ultimately even take his life. There are good support groups for family members of addicts that can guide you. Have your physician or some other wise person direct you.

Disease of Addiction: Addiction is actually a family disease. Many members of the families of an addict can be deeply hurt or affected by a loved one's addiction. There is a great program for family members, called Al-Anon. There you will learn you cannot control or change your father. And you will learn you did not cause his disease. You may get help there also to learn how to confront an addict appropriately.

Your father has to: recognize that he has a problem and he has to want to do something about it. Families often feel helpless, hopeless, angry, ashamed and guilty, in various combinations. Concerned family members can present their worries to him trying to help him see the problem, but this often results in denial and anger on her part. Attend Alanon meetings for your own sake, not hers, it may help with enabling.
