The various alcohol and drug abuse rehabilitation services which are available to drug addicted people in Acton, California can differ in many different ways. Quite a few substance abuse treatment programs are conducted in a residential or inpatient location, where clients remain the entire time they are in rehabilitation which provides a more conducive rehab environment. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be an appropriate substance abuse rehab program for people in Acton who are having difficulties with long term drug addiction issues. Whether inpatient or outpatient alcohol and drug abuse treatment services are selected, there are varying amounts of time that men and women will be asked to stay in the drug treatment facility. For example, quite a few short-term programs offer services for 30 days or less, whereas long-term centers will demand at least a 12 week stay.
