The various alcohol and drug abuse treatment services which are offered to drug addicted people in Lehman can differ in many various ways. Quite a few alcohol and drug abuse rehabilitation services are offered in a residential or inpatient location, where clients remain the entire time they are in rehab which provides a more therapeutic rehab environment. Others provide substance abuse treatment programs on an outpatient basis which allows for more versatility, though outpatient centers are not always a suitable drug and alcohol abuse rehab program for people in Lehman who are struggling with long term addiction issues. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are chosen, there are also different lengths of time that people will be expected to stay in the drug rehabilitation program. For instance, many short-term programs offer programs for 30 days or less, whereas long-term programs will require at least a 12 week stay.
