The various alcohol and drug abuse rehab services which are accessible to alcohol and drug addicted people in Bangor can vary in many different ways. Quite a few alcohol and drug abuse treatment programs take place in a residential or inpatient facility, where clients remain the entire time they are in treatment which offers a more conducive treatment environment. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, although outpatient centers are not always an appropriate substance abuse treatment program for individuals in Bangor who are having difficulties with long term drug addiction difficulties. Whether inpatient or outpatient substance abuse rehabilitation services are selected, there are varying amounts of time that people will be required to remain in the alcohol and drug treatment program. For instance, many short-term programs provide programs for a month or less, while long-term facilities will call for at least a 12 week stay.
