Due to an unforeseen injury that causes multiple problems, my brother again lives with our parents. To our knowledge, he hasn't used hard drugs in over a decade. However, his addict thinking and behaviors never died. He's been an alcoholic most of his life, and he smokes pot because, according to him, it slows his racing thoughts, many of which involve retaliation. Because of the injury, he takes medications whose labels warn not to mix with alcohol. Telling him he has an addiction or that he's an alcoholic doesn't help. Have any parents here suffered from their adult child's addiction--drugs or alcohol? What successful methods have you or someone you know used in nudging their loved one toward changing their lives for the better?
