The different alcohol and drug abuse treatment programs which are accessible to drug addicted people in Salem can differ in many various ways. Some alcohol and drug abuse rehabilitation programs are offered in a residential or inpatient location, where individuals reside the entire time they are in rehab which offers a more therapeutic rehab environment. Others provide drug and alcohol abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be an appropriate substance abuse rehab service for people in Salem who are having difficulties with long term drug or alcohol addiction problems. Whether inpatient or outpatient drug and alcohol abuse rehabilitation services are selected, there are varying lengths of time that men and women will be asked to continue to be in the alcohol and drug rehabilitation program. For instance, quite a few short-term programs provide services for 4 weeks or less, while long-term facilities will call for at least a 3 month stay.
