The various substance abuse rehabilitation services which are available to drug and alcohol addicted people in Willow can differ in several different ways. Some drug and alcohol abuse treatment services are offered in a residential or inpatient facility, where clients reside for the duration of their rehab which provides a more conducive treatment environment. Others provide substance abuse rehabilitation services on an outpatient basis which allows for more flexibility, though outpatient centers may not be an appropriate substance abuse rehab service for men and women in Willow who are having difficulties with long term addiction problems. Whether inpatient or outpatient drug and alcohol abuse rehabilitation programs are selected, there are varying amounts of time that men and women will be expected to stay in the drug and alcohol treatment program. For instance, quite a few short-term programs provide programs for 4 weeks or less, whereas long-term facilities will demand at least a 90 day stay.
