The various alcohol and drug abuse rehab programs which are offered to drug and alcohol addicted individuals in Tarrs can vary in many different ways. Some substance abuse rehabilitation services take place in a residential or inpatient facility, where individuals remain for the duration of their rehabilitation which supplies a more therapeutic treatment setting. Others provide substance abuse rehab programs on an outpatient basis which provides a sense of flexibility, though outpatient centers may not be an appropriate substance abuse rehab service for people in Tarrs who are having difficulties with serious drug or alcohol addiction difficulties. Whether inpatient or outpatient drug and alcohol abuse treatment services are chosen, there are varying amounts of time that people will be expected to remain in the alcohol and drug treatment facility. For example, quite a few short-term programs provide programs for a month or less, while long-term centers will call for at least a 12 week stay.
