The various drug and alcohol abuse treatment programs which are available to drug addicted persons in Normandy can vary in a lot of different ways. Quite a few alcohol and drug abuse rehab programs are conducted in a residential or inpatient location, where clients remain for the duration of their treatment which supplies a more conducive rehabilitation environment. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, although outpatient programs may not be a suitable substance abuse rehabilitation service for individuals in Normandy who are having difficulties with long term drug addiction problems. Whether or not inpatient or outpatient drug and alcohol abuse rehab services are selected, there are varying lengths of time that individuals will be asked to remain in the alcohol and drug treatment facility. For instance, many short-term programs offer services for a month or less, while long-term facilities will require at least a 3 month stay.
