The different substance abuse treatment programs which are available to alcohol and drug addicted people in Greensburg can differ in several various ways. Some drug and alcohol abuse rehab programs take place in a residential or inpatient facility, where individuals reside for the duration of their rehabilitation which provides a more conducive rehab environment. Others offer substance abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be an appropriate substance abuse rehabilitation program for individuals in Greensburg who are having difficulties with serious addiction problems. Whether or not inpatient or outpatient alcohol and drug abuse treatment programs are selected, there are also different lengths of time that individuals will be asked to remain in the drug rehab facility. For example, some short-term programs offer services for a month or less, whereas long-term facilities will call for at least a 12 week stay.
