The different drug and alcohol abuse treatment programs which are accessible to alcohol and drug addicted persons in Essex can vary in many different ways. Some substance abuse treatment services are conducted in a residential or inpatient setting, where clients remain the entire time they are in rehab which offers a more conducive rehab setting. Others offer drug and alcohol abuse treatment programs on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be an appropriate drug and alcohol abuse rehabilitation program for people in Essex who are having difficulties with long term drug addiction problems. Whether inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are also different lengths of time that men and women will be expected to stay in the alcohol and drug rehabilitation facility. For instance, many short-term programs provide services for a month or less, whereas long-term facilities will call for at least a 90 day stay.
