The diverse substance abuse rehabilitation programs which are offered to drug addicted persons in Mountain View, California can vary in several various ways. Some alcohol and drug abuse treatment programs take place in a residential or inpatient location, where clients reside the entire time they are in rehab which provides a more conducive rehabilitation setting. Others offer drug and alcohol abuse rehabilitation services on an outpatient basis which provides a sense of flexibility, though outpatient programs may not be an appropriate alcohol and drug abuse rehabilitation service for people in Mountain View who are struggling with serious drug or alcohol addiction difficulties. Whether inpatient or outpatient substance abuse rehab services are chosen, there are also different lengths of time that individuals will be asked to remain in the drug rehab center. For example, many short-term programs provide services for a month or less, while long-term facilities will demand at least a 3 month stay.
