The diverse drug and alcohol abuse treatment services which are accessible to drug addicted individuals in Unalaska can vary in many different ways. Quite a few alcohol and drug abuse rehabilitation services take place in a residential or inpatient location, where clients remain the entire time they are in rehab which supplies a more conducive treatment environment. Others offer drug and alcohol abuse rehabilitation programs on an outpatient basis which allows for more flexibility, though outpatient centers may not be a suitable drug and alcohol abuse rehab service for people in Unalaska who are having difficulties with long term drug or alcohol addiction problems. Regardless of whether inpatient or outpatient substance abuse rehabilitation programs are selected, there are varying lengths of time that men and women will be asked to continue to be in the drug and alcohol rehab facility. For example, quite a few short-term programs provide programs for 30 days or less, while long-term centers will demand at least a 12 week stay.
