The diverse drug and alcohol abuse rehabilitation services which are offered to drug addicted people in Swansea can differ in a lot of different ways. Some substance abuse rehabilitation services are offered in a residential or inpatient location, where individuals reside for the duration of their rehab which provides a more therapeutic rehabilitation environment. Others offer drug and alcohol abuse treatment programs on an outpatient basis which provides a sense of flexibility, although outpatient facilities are not always a suitable substance abuse rehab service for people in Swansea who are struggling with serious drug or alcohol addiction issues. Whether inpatient or outpatient drug and alcohol abuse rehab services are chosen, there are also different lengths of time that people will be required to stay in the drug and alcohol treatment center. For example, some short-term programs provide services for 30 days or less, whereas long-term centers will require at least a 90 day stay.
