The various alcohol and drug abuse rehabilitation services which are accessible to drug and alcohol addicted persons in Holtsville can differ in several various ways. Some drug and alcohol abuse rehabilitation programs are offered in a residential or inpatient location, where clients remain for the duration of their rehabilitation which offers a more conducive treatment setting. Others provide alcohol and drug abuse rehabilitation services on an outpatient basis which provides a sense of flexibility, though outpatient centers are not always an appropriate drug and alcohol abuse treatment program for men and women in Holtsville who are having difficulties with serious drug addiction difficulties. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are selected, there are varying lengths of time that individuals will be required to remain in the drug and alcohol rehabilitation program. For example, many short-term programs provide programs for a month or less, while long-term centers will require at least a 90 day stay.
