The different substance abuse rehabilitation programs which are offered to alcohol and drug addicted persons in Hillsborough can vary in many various ways. Quite a few alcohol and drug abuse rehabilitation services are conducted in a residential or inpatient facility, where individuals reside the entire time they are in treatment which provides a more conducive rehabilitation setting. Others provide substance abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be an appropriate substance abuse treatment service for individuals in Hillsborough who are having difficulties with serious addiction problems. Whether or not inpatient or outpatient substance abuse treatment programs are chosen, there are varying lengths of time that people will be required to remain in the drug treatment facility. For instance, quite a few short-term programs provide programs for 30 days or less, whereas long-term centers will call for at least a 12 week stay.
