Enrolling into a residential long-term treatment program (more than 30 days) is the best way ofapproaching a serious substance abuse problem. This type of drug rehab program is more comprehensive 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 treatment program (more than 30 days) means that you as the client will reside at the treatment center 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 or alcohol rehab facilities are an excellent choice for those who have a long history of substance abuse or who have had other unsuccessful attempts at recovery in the past.
