Attending a residential long-term treatment program (more than 30 days) is the best way ofresolving a severe substance abuse problem. This type of drug and alcohol rehabilitation 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 treatment program (more than 30 days) means that you as the client will reside at the rehab center around the clock while you are in recovery. While providing a more relaxed home-like environment the individual has access to treatment professionals at all times. Long term drug or alcohol treatment facilities are an ideal choice for those who have a long history of addiction or who have had other unsuccessful attempts at recovery in the past.
