The various substance abuse treatment services which are offered to alcohol and drug addicted persons in Greenfield Center can vary in several different ways. Some alcohol and drug abuse rehabilitation programs take place in a residential or inpatient facility, where individuals remain the entire time they are in rehab which provides a more therapeutic rehabilitation setting. Others provide substance abuse rehab services on an outpatient basis which provides a sense of flexibility, though outpatient programs are not always a suitable substance abuse rehab program for individuals in Greenfield Center who are struggling with long term addiction issues. Whether inpatient or outpatient drug and alcohol abuse rehab services are selected, there are also different amounts of time that individuals will be required to continue to be in the drug treatment program. For instance, some short-term programs provide services for 30 days or less, whereas long-term centers will demand at least a 12 week stay.
