The diverse substance abuse rehabilitation programs which are available to alcohol and drug addicted people in Newfoundland can differ in a lot of various ways. Quite a few substance abuse rehabilitation services are offered in a residential or inpatient setting, where clientele remain the entire time they are in treatment which provides a more therapeutic rehabilitation environment. Others offer drug and alcohol abuse rehab services on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be a suitable alcohol and drug abuse treatment service for individuals in Newfoundland who are having difficulties with long term drug addiction issues. Regardless of whether inpatient or outpatient substance abuse rehabilitation services are selected, there are varying amounts of time that people will be expected to continue to be in the drug rehabilitation program. For example, quite a few short-term programs provide programs for 4 weeks or less, while long-term programs will demand at least a 90 day stay.
