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 rehabilitation 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 stay at the treatment facility around the clock while you are in recovery. While offering a more relaxed home-like setting the person has access to counselors and staff at all times. Long term drug or alcohol rehab centers are a perfect choice for those who have a long history of addiction or who have had other unsuccessful attempts at recovery in the past.
