The diverse substance abuse rehab programs which are accessible to drug addicted persons in Oak Ridge can vary in a lot of various ways. Some drug and alcohol abuse rehab services are conducted in a residential or inpatient facility, where clients remain the entire time they are in rehab which provides a more conducive rehabilitation environment. Others provide drug and alcohol abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient facilities may not be an appropriate substance abuse rehab service for men and women in Oak Ridge who are struggling with serious drug or alcohol addiction difficulties. Whether inpatient or outpatient substance abuse treatment programs are chosen, there are also different amounts of time that people will be asked to remain in the alcohol and drug treatment center. For instance, many short-term programs offer programs for 30 days or less, while long-term facilities will require at least a 12 week stay.
