Attending a residential long-term treatment program (more than 30 days) is an effective way ofresolving a serious drug or alcohol addiction problem. This type of drug and alcohol rehab program 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. Choosing a residential long-term rehab program (more than 30 days) means that you as the client will reside at the rehab facility around the clock while you are in recovery. While offering a more relaxed home-like environment the person has access to treatment professionals at all times. Long term drug rehab 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.
