The different substance abuse treatment programs which are offered to alcohol and drug addicted persons in Woburn can differ in a lot of various ways. Some drug and alcohol abuse treatment services are conducted in a residential or inpatient facility, where individuals remain the entire time they are in treatment which supplies a more conducive treatment setting. Others offer drug and alcohol abuse rehabilitation services on an outpatient basis which allows for more flexibility, although outpatient centers are not always an appropriate substance abuse rehab service for men and women in Woburn who are having difficulties with long term drug addiction problems. Whether or not inpatient or outpatient substance abuse rehabilitation services are selected, there are also different lengths of time that people will be expected to continue to be in the drug and alcohol rehabilitation facility. For instance, many short-term programs offer programs for a month or less, while long-term programs will call for at least a 12 week stay.
