Enrolling into a residential long-term treatment facility (more than 30 days) is the best way ofresolving a severe substance abuse problem. This type of substance abuse rehab facility 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. Choosing a residential long-term rehabilitation program (more than 30 days) means that you as the client will reside at the rehabilitation facility 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 treatment centers are an ideal 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.
