The diverse drug and alcohol abuse treatment services which are accessible to alcohol and drug addicted individuals in Granville can differ in several various ways. Quite a few alcohol and drug abuse rehab programs are offered in a residential or inpatient setting, where clients remain for the duration of their rehab which provides a more therapeutic rehab environment. Others provide alcohol and drug abuse rehabilitation programs on an outpatient basis which provides a sense of versatility, although outpatient centers may not be a suitable drug and alcohol abuse treatment service for individuals in Granville who are having difficulties with long term drug or alcohol addiction problems. Regardless of whether inpatient or outpatient drug and alcohol abuse rehab programs are selected, there are also different amounts of time that people will be required to remain in the alcohol and drug rehab center. For example, many short-term programs provide programs for a month or less, while long-term programs will call for at least a 12 week stay.
