The different drug and alcohol abuse rehabilitation programs which are available to drug and alcohol addicted people in Yorktown can vary in many various ways. Quite a few substance abuse rehab programs are offered in a residential or inpatient location, where individuals reside for the duration of their treatment which provides a more therapeutic rehabilitation environment. Others provide drug and alcohol abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be an appropriate alcohol and drug abuse treatment program for individuals in Yorktown who are struggling with serious drug addiction difficulties. Regardless of whether inpatient or outpatient substance abuse rehab services are selected, there are varying lengths of time that people will be required to remain in the alcohol and drug treatment center. For example, many short-term programs offer services for 4 weeks or less, whereas long-term programs will demand at least a 3 month stay.
