The different drug and alcohol abuse rehabilitation services which are accessible to alcohol and drug addicted individuals in Hamilton can vary in a lot of different ways. Some alcohol and drug abuse rehabilitation services are offered in a residential or inpatient setting, where individuals reside the entire time they are in treatment which provides a more therapeutic rehab environment. Others provide alcohol and drug abuse rehabilitation services on an outpatient basis which allows for more flexibility, though outpatient centers are not always a suitable substance abuse treatment service for people in Hamilton who are having difficulties with long term drug addiction issues. Whether or not inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are also different lengths of time that individuals will be asked to continue to be in the alcohol and drug rehab center. For example, quite a few short-term programs offer services for 30 days or less, whereas long-term facilities will call for at least a 90 day stay.
