Attending a residential long-term treatment program (more than 30 days) is an effective way ofresolving a severe drug or alcohol addiction problem. This type of substance abuse 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 rehabilitation program (more than 30 days) means that you as the client will live at the rehab center around the clock while you are in recovery. While offering a more relaxed home-like atmosphere the individual has access to counselors and staff at all times. Long term drug treatment centers are a perfect 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.
