The diverse substance abuse rehab programs which are offered to drug addicted persons in Fairfield can differ in many various ways. Some substance abuse treatment services are conducted in a residential or inpatient location, where clients reside the entire time they are in rehabilitation which provides a more therapeutic rehabilitation setting. Others provide drug and alcohol abuse rehab services on an outpatient basis which allows for more flexibility, although outpatient facilities may not be an appropriate drug and alcohol abuse rehabilitation service for individuals in Fairfield who are having difficulties with serious drug addiction difficulties. Whether or not inpatient or outpatient substance abuse treatment services are selected, there are varying lengths of time that men and women will be required to stay in the alcohol and drug rehabilitation program. For example, quite a few short-term programs offer programs for a month or less, while long-term programs will require at least a 90 day stay.
