The various drug and alcohol abuse rehab services which are accessible to drug and alcohol addicted people in Elkhart, Illinois can differ in a lot of different ways. Some substance abuse rehab programs are conducted in a residential or inpatient setting, where clients remain the entire time they are in treatment which offers a more therapeutic rehabilitation environment. Others offer alcohol and drug abuse rehabilitation programs on an outpatient basis which provides a sense of flexibility, although outpatient programs are not always an appropriate drug and alcohol abuse treatment program for people in Elkhart, Illinois who are struggling with long term addiction difficulties. Whether or not inpatient or outpatient alcohol and drug abuse rehabilitation services are selected, there are also different lengths of time that individuals will be required to remain in the drug rehabilitation center. For example, many short-term programs provide services for 30 days or less, whereas long-term centers will require at least a 90 day stay.
