The various drug and alcohol abuse treatment programs which are accessible to alcohol and drug addicted individuals in Penhook can vary in many various ways. Some substance abuse rehab services are offered in a residential or inpatient setting, where clients remain for the duration of their treatment which offers a more conducive rehabilitation environment. Others provide alcohol and drug abuse treatment programs on an outpatient basis which allows for more flexibility, although outpatient centers are not always an appropriate substance abuse treatment service for individuals in Penhook who are having difficulties with long term addiction problems. Whether or not inpatient or outpatient alcohol and drug abuse rehab services are chosen, there are also different lengths of time that people will be expected to stay in the drug and alcohol treatment center. For instance, some short-term programs provide services for a month or less, while long-term programs will require at least a 12 week stay.
