The diverse alcohol and drug abuse treatment services which are accessible to alcohol and drug addicted persons in Granby can differ in several different ways. Quite a few alcohol and drug abuse treatment services are conducted in a residential or inpatient setting, where individuals remain the entire time they are in rehabilitation which provides a more therapeutic rehabilitation environment. Others provide substance abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient facilities may not be an appropriate drug and alcohol abuse treatment program for people in Granby who are having difficulties with serious addiction issues. Whether inpatient or outpatient alcohol and drug abuse treatment programs are selected, there are also different lengths of time that people will be required to stay in the drug and alcohol rehab center. For instance, quite a few short-term programs offer programs for 30 days or less, while long-term programs will require at least a 90 day stay.
