Enrolling into a residential long-term treatment facility (more than 30 days) is the best way ofaddressing a severe drug or alcohol addiction problem. This type of substance abuse rehabilitation facility 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 rehab 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 person has access to treatment professionals at all times. Long term drug rehab facilities are a perfect choice for those who have a long history of substance abuse or who have had other unsuccessful attempts at recovery in the past.
