The different drug and alcohol abuse rehabilitation programs which are accessible to drug and alcohol addicted persons in Evergreen can differ in many various ways. Some substance abuse treatment programs are offered in a residential or inpatient facility, where clients remain for the duration of their rehabilitation which offers a more conducive treatment environment. Others offer drug and alcohol abuse treatment services on an outpatient basis which allows for more versatility, though outpatient centers are not always a suitable alcohol and drug abuse rehab service for individuals in Evergreen who are having difficulties with long term drug or alcohol addiction difficulties. Whether or not inpatient or outpatient drug and alcohol abuse rehab programs are selected, there are varying lengths of time that men and women will be required to remain in the drug treatment facility. For example, quite a few short-term programs provide programs for a month or less, whereas long-term centers will demand at least a 90 day stay.
