The various drug and alcohol abuse rehab services which are available to alcohol and drug addicted people in Grand Rivers can differ in many different ways. Some drug and alcohol abuse rehab programs are offered in a residential or inpatient facility, where clients remain the entire time they are in rehabilitation which provides a more therapeutic rehab environment. Others offer alcohol and drug abuse treatment services on an outpatient basis which provides a sense of versatility, although outpatient centers are not always an appropriate drug and alcohol abuse rehabilitation program for individuals in Grand Rivers who are having difficulties with serious drug or alcohol addiction issues. Whether inpatient or outpatient substance abuse treatment programs are selected, there are also different amounts of time that individuals will be required to stay in the drug rehabilitation program. For example, quite a few short-term programs provide services for a month or less, whereas long-term programs will demand at least a 12 week stay.
