The different drug and alcohol abuse rehabilitation services which are available to drug addicted persons in Downey, California can differ in many various ways. Quite a few substance abuse rehabilitation services are conducted in a residential or inpatient facility, where clients reside the entire time they are in rehab which supplies a more therapeutic rehab environment. Others offer drug and alcohol abuse rehab services on an outpatient basis which allows for more versatility, although outpatient programs are not always a suitable drug and alcohol abuse rehab service for men and women in Downey who are having difficulties with serious drug or alcohol addiction difficulties. Whether inpatient or outpatient drug and alcohol abuse rehab services are selected, there are also different lengths of time that people will be expected to remain in the drug and alcohol treatment program. For example, many short-term programs provide services for a month or less, whereas long-term programs will require at least a 90 day stay.
