The various substance abuse rehab services which are offered to drug addicted people in Louisa can vary in many different ways. Quite a few drug and alcohol abuse treatment services take place in a residential or inpatient setting, where clients reside the entire time they are in rehab which provides a more therapeutic rehabilitation setting. Others provide drug and alcohol abuse rehabilitation services on an outpatient basis which provides a sense of versatility, although outpatient centers may not be a suitable substance abuse treatment service for men and women in Louisa who are having difficulties with long term addiction problems. Whether inpatient or outpatient drug and alcohol abuse treatment services are selected, there are also different lengths of time that individuals will be asked to stay in the alcohol and drug rehabilitation program. For instance, some short-term programs provide programs for 4 weeks or less, whereas long-term centers will require at least a 90 day stay.
