The different substance abuse treatment services which are available to drug and alcohol addicted persons in Appalachia can vary in many different ways. Quite a few alcohol and drug abuse rehabilitation programs are conducted in a residential or inpatient location, where clients reside the entire time they are in rehab which provides a more therapeutic rehab setting. Others offer alcohol and drug abuse treatment services on an outpatient basis which provides a sense of versatility, though outpatient programs are not always an appropriate substance abuse rehab program for men and women in Appalachia who are struggling with long term drug addiction difficulties. Regardless of whether inpatient or outpatient alcohol and drug abuse treatment services are selected, there are also different lengths of time that individuals will be expected to stay in the drug and alcohol rehabilitation program. For example, some short-term programs provide programs for a month or less, whereas long-term programs will demand at least a 12 week stay.
