The different substance abuse treatment programs which are available to alcohol and drug addicted persons in Walhalla can differ in several various ways. Quite a few alcohol and drug abuse rehab programs are conducted in a residential or inpatient location, where individuals reside the entire time they are in rehab which offers a more conducive rehabilitation setting. Others provide drug and alcohol abuse rehabilitation programs on an outpatient basis which provides a sense of versatility, although outpatient facilities may not be an appropriate drug and alcohol abuse rehab service for people in Walhalla who are having difficulties with serious addiction issues. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are selected, there are varying amounts of time that people will be required to remain in the alcohol and drug treatment program. For instance, many short-term programs provide programs for a month or less, while long-term facilities will require at least a 12 week stay.
