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