Attending a residential long-term treatment program (more than 30 days) is an effective way ofaddressing a serious substance abuse problem. This type of drug rehabilitation facility is more intensive 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 stay at the rehabilitation facility around the clock while you are in recovery. While providing a more relaxed home-like setting the client has access to treatment professionals at all times. Long term drug rehabilitation facilities are an excellent choice for those who have a long history of addiction or who have had other unsuccessful attempts at drug or alcohol treatment in the past.
