Enrolling into a residential long-term treatment facility (more than 30 days) is the best way ofaddressing a severe drug or alcohol addiction problem. This type of substance abuse rehab facility is more comprehensive 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 treatment 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 setting the client has access to treatment professionals at all times. Long term drug or alcohol rehab programs are an perfect choice for those who have a long history of substance abuse or who have had other unsuccessful attempts at recovery in the past.
