The different substance abuse rehabilitation programs which are available to drug addicted people in Elmsford can vary in many different ways. Some drug and alcohol abuse rehab programs take place in a residential or inpatient setting, where individuals remain for the duration of their rehab which provides a more conducive rehab environment. Others provide substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, though outpatient centers may not be a suitable alcohol and drug abuse rehab program for people in Elmsford who are struggling with long term drug addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehabilitation programs are chosen, there are also different lengths of time that people will be asked to remain in the alcohol and drug rehabilitation program. For example, some short-term programs offer programs for 4 weeks or less, while long-term facilities will call for at least a 12 week stay.
