The diverse drug and alcohol abuse treatment programs which are offered to drug and alcohol addicted people in Portland, CT. can differ in a lot of different ways. Quite a few substance abuse rehab programs are offered in a residential or inpatient facility, where clients reside for the duration of their rehabilitation which provides a more therapeutic rehabilitation environment. Others provide alcohol and drug abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient programs are not always an appropriate alcohol and drug abuse rehabilitation service for men and women in Portland, CT. who are having difficulties with long term addiction problems. Whether inpatient or outpatient alcohol and drug abuse treatment services are selected, there are varying lengths of time that people will be asked to continue to be in the drug treatment program. For example, many short-term programs offer services for a month or less, whereas long-term programs will call for at least a 12 week stay.
