Attending a residential long-term treatment facility (more than 30 days) is an effective way ofapproaching a severe substance abuse problem. This type of substance abuse rehabilitation program 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. Choosing a residential long-term rehabilitation program (more than 30 days) means that you as the client will live at the rehab center around the clock while you are in recovery. While providing a more relaxed home-like atmosphere the person has access to treatment professionals at all times. Long term drug or alcohol rehabilitation centers are an ideal choice for those who have a long history of substance abuse or who have had other unsuccessful attempts at recovery in the past.
