The different alcohol and drug abuse rehab services which are offered to alcohol and drug addicted persons in Arnold, California can differ in a lot of various ways. Quite a few substance abuse treatment programs are conducted in a residential or inpatient setting, where clients reside the entire time they are in rehab which provides a more conducive rehabilitation setting. Others provide drug and alcohol abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be a suitable alcohol and drug abuse rehab program for individuals in Arnold who are having difficulties with serious drug or alcohol addiction problems. Whether inpatient or outpatient drug and alcohol abuse rehabilitation services are selected, there are varying amounts of time that men and women will be asked to continue to be in the drug rehabilitation center. For instance, some short-term programs provide services for 4 weeks or less, whereas long-term facilities will require at least a 3 month stay.
