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