Attending a residential long-term treatment program (more than 30 days) is an effective way ofapproaching 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 person in recovery 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 reside at the rehabilitation center around the clock while you are in recovery. While offering a more relaxed home-like environment the individual has access to counselors and staff at all times. Long term drug rehab programs 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.
