The different alcohol and drug abuse rehab services which are offered to alcohol and drug addicted persons in Hernshaw can differ in a lot of different ways. Quite a few drug and alcohol abuse treatment services take place in a residential or inpatient facility, where clients remain for the duration of their treatment which offers a more therapeutic rehab setting. Others provide 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 rehabilitation service for individuals in Hernshaw who are struggling with long term 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 required to remain in the drug rehab facility. For example, quite a few short-term programs offer services for 4 weeks or less, while long-term programs will demand at least a 90 day stay.
