The various substance abuse treatment programs which are available to drug and alcohol addicted persons in Virginia State University can vary in a lot of various ways. Some substance abuse rehab services are offered in a residential or inpatient setting, where individuals reside for the duration of their treatment which provides a more conducive rehabilitation environment.
