The different drug and alcohol abuse rehabilitation services which are accessible to drug addicted people in West can differ in many different ways. Quite a few drug and alcohol abuse rehabilitation programs are conducted in a residential or inpatient setting, where clients reside for the duration of their treatment which provides a more therapeutic treatment environment. Others offer substance abuse treatment services on an outpatient basis which allows for more versatility, though outpatient centers are not always an appropriate substance abuse treatment service for individuals in West who are struggling with long term drug or alcohol addiction issues. Regardless of whether inpatient or outpatient drug and alcohol abuse rehab services are chosen, there are also different lengths of time that men and women will be required to stay in the drug and alcohol treatment program. For instance, quite a few short-term programs provide programs for 4 weeks or less, while long-term centers will demand at least a 12 week stay.
