The different drug and alcohol abuse rehabilitation programs which are offered to drug addicted persons in Amherst, VA. can differ in many different ways. Some alcohol and drug abuse rehab programs are offered in a residential or inpatient location, where individuals reside the entire time they are in treatment which supplies a more therapeutic rehab environment.
