The diverse alcohol and drug abuse rehabilitation programs which are available to drug and alcohol addicted individuals in Northridge, California can differ in several different ways. Quite a few alcohol and drug abuse treatment programs are conducted in a residential or inpatient facility, where individuals reside the entire time they are in treatment which provides a more therapeutic rehabilitation setting. Others provide alcohol and drug abuse rehab services on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be an appropriate alcohol and drug abuse rehabilitation program for people in Northridge who are having difficulties with serious drug addiction issues. Whether inpatient or outpatient substance abuse rehab services are chosen, there are varying lengths of time that individuals will be asked to remain in the drug rehabilitation center. For example, many short-term programs provide services for 30 days or less, while long-term centers will demand at least a 3 month stay.
