Attending a residential long-term treatment program (more than 30 days) is the best way ofapproaching a serious substance abuse problem. This type of substance abuse rehabilitation facility is more intensive than others that only last a few weeks or those where the client is free to come and go as they please. Attending a residential long-term rehab program (more than 30 days) means that you as the client will live at the rehabilitation center around the clock while you are in recovery. While offering a more relaxed home-like atmosphere the person has access to counselors and staff at all times. Long term drug or alcohol treatment facilities are an ideal choice for those who have a long history of addiction or who have had other unsuccessful attempts at drug or alcohol treatment in the past.
