The various alcohol and drug abuse rehabilitation services which are offered to alcohol and drug addicted individuals in Carlyle can vary in many different ways. Quite a few drug and alcohol abuse rehabilitation services take place in a residential or inpatient setting, where clients remain for the duration of their treatment which offers a more conducive rehabilitation environment. Others offer substance abuse treatment services on an outpatient basis which allows for more flexibility, though outpatient facilities are not always an appropriate substance abuse rehabilitation program for people in Carlyle who are having difficulties with long term addiction difficulties. Whether inpatient or outpatient alcohol and drug abuse rehabilitation programs are selected, there are varying lengths of time that people will be expected to remain in the alcohol and drug rehab facility. For example, many short-term programs offer services for 4 weeks or less, whereas long-term centers will demand at least a 3 month stay.
