The different substance abuse treatment programs which are offered to alcohol and drug addicted people in Altavista can differ in many various ways. Quite a few substance abuse rehab programs take place in a residential or inpatient setting, where individuals reside for the duration of their rehabilitation which provides a more therapeutic treatment setting. Others provide alcohol and drug abuse rehabilitation programs on an outpatient basis which provides a sense of versatility, although outpatient centers are not always a suitable substance abuse treatment program for people in Altavista who are having difficulties with serious drug or alcohol addiction problems. Whether or not 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 treatment program. For example, quite a few short-term programs offer services for a month or less, while long-term facilities will require at least a 90 day stay.
