Attending a residential long-term treatment facility (more than 30 days) is an effective way ofaddressing 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. Choosing a residential long-term rehabilitation 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 environment the person has access to treatment professionals at all times. Long term drug or alcohol rehab centers are an excellent choice for those who have a long history of substance abuse or who have had other unsuccessful attempts at recovery in the past.
