The different substance abuse rehab services which are offered to alcohol and drug addicted people in Marietta can differ in many different ways. Quite a few drug and alcohol abuse treatment programs are offered in a residential or inpatient setting, where clients remain the entire time they are in rehab which offers a more conducive rehab environment. Others offer substance abuse rehabilitation programs on an outpatient basis which allows for more versatility, though outpatient centers may not be a suitable substance abuse treatment program for people in Marietta who are struggling with serious drug or alcohol addiction problems. Whether or not inpatient or outpatient alcohol and drug abuse treatment programs are selected, there are varying lengths of time that men and women will be asked to stay in the drug and alcohol treatment center. For example, some short-term programs offer services for 4 weeks or less, whereas long-term facilities will require at least a 12 week stay.
