The different drug and alcohol abuse treatment services which are offered to drug and alcohol addicted people in New Castle can vary in several different ways. Quite a few substance abuse treatment programs are conducted in a residential or inpatient setting, where individuals reside the entire time they are in rehabilitation which provides a more conducive treatment setting. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, though outpatient programs may not be a suitable substance abuse rehab program for individuals in New Castle who are struggling with serious drug or alcohol addiction problems. Whether inpatient or outpatient alcohol and drug abuse rehab programs are selected, there are also different lengths of time that men and women will be required to remain in the alcohol and drug treatment center. For example, many short-term programs offer services for 30 days or less, whereas long-term programs will call for at least a 12 week stay.
