The different substance abuse rehab programs which are offered to alcohol and drug addicted persons in Port Huron can differ in several various ways. Quite a few substance abuse treatment programs are conducted in a residential or inpatient setting, where clients reside the entire time they are in rehabilitation which provides a more conducive rehabilitation setting. Others provide substance abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be a suitable drug and alcohol abuse rehab program for individuals in Port Huron who are struggling with long term drug addiction difficulties. Whether or not inpatient or outpatient alcohol and drug abuse rehab programs are selected, there are varying amounts of time that individuals will be expected to stay in the drug and alcohol rehabilitation program. For instance, some short-term programs provide services for 30 days or less, whereas long-term programs will require at least a 12 week stay.
