Enrolling into a residential long-term treatment program (more than 30 days) is an effective way ofaddressing a severe drug or alcohol addiction problem. This type of drug rehabilitation 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 live at the rehabilitation center around the clock while you are in recovery. While providing a more relaxed home-like environment the person has access to treatment professionals at all times. Long term drug or alcohol treatment centers are an excellent choice for those who have a long history of addiction or who have had other unsuccessful attempts at recovery in the past.
