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