The various drug and alcohol abuse rehabilitation programs which are accessible to drug addicted persons in Fairfield can vary in several different ways. Some substance abuse rehabilitation programs take place in a residential or inpatient facility, where clients remain for the duration of their rehab which provides a more conducive treatment environment. Others offer drug and alcohol abuse treatment services on an outpatient basis which allows for more versatility, although outpatient programs are not always an appropriate substance abuse rehab service for men and women in Fairfield who are struggling with serious drug addiction difficulties. Whether inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are varying lengths of time that men and women will be required to remain in the drug rehabilitation facility. For instance, quite a few short-term programs provide programs for 4 weeks or less, whereas long-term centers will require at least a 12 week stay.
