Enrolling into a residential long-term treatment program (more than 30 days) is an effective way ofaddressing a serious substance abuse problem. This type of substance abuse rehab 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 stay at the rehabilitation center around the clock while you are in recovery. While offering a more relaxed home-like atmosphere the individual has access to treatment professionals at all times. Long term drug or alcohol rehabilitation facilities are an excellent 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.
