The different alcohol and drug abuse treatment services which are offered to drug and alcohol addicted people in Thiells can vary in several different ways. Some substance abuse treatment programs are conducted in a residential or inpatient location, where clients reside the entire time they are in treatment which offers a more therapeutic rehabilitation environment. Others offer substance abuse rehab services on an outpatient basis which allows for more flexibility, although outpatient centers are not always a suitable substance abuse treatment service for individuals in Thiells who are having difficulties with serious drug addiction difficulties. Whether inpatient or outpatient drug and alcohol abuse rehabilitation programs are chosen, there are varying amounts of time that individuals will be expected to stay in the drug rehab facility. For example, many short-term programs provide programs for 30 days or less, while long-term centers will call for at least a 12 week stay.
