The diverse substance abuse rehab services which are offered to alcohol and drug addicted people in Fairfield can differ in many various ways. Some substance abuse rehab services are offered in a residential or inpatient setting, where individuals reside for the duration of their rehabilitation which offers a more therapeutic rehabilitation environment. Others provide drug and alcohol abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient programs are not always an appropriate alcohol and drug abuse treatment program for people in Fairfield who are struggling with long term drug or alcohol addiction problems. Whether or not inpatient or outpatient drug and alcohol abuse rehabilitation services are chosen, there are also different lengths of time that people will be expected to remain in the drug and alcohol treatment program. For example, some short-term programs provide programs for 4 weeks or less, whereas long-term facilities will call for at least a 90 day stay.
