Attending a residential long-term treatment facility (more than 30 days) is the best way ofapproaching a severe substance abuse problem. This type of substance abuse treatment 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. Attending a residential long-term treatment program (more than 30 days) means that you as the client will live at the treatment center around the clock while you are in recovery. While offering a more relaxed home-like setting the client has access to treatment professionals at all times. Long term drug rehab centers are an excellent choice for those who have a long history of addiction or who have had other unsuccessful attempts at recovery in the past.
