The different drug and alcohol abuse rehabilitation services which are available to drug and alcohol addicted people in Andover can vary in several different ways. Some alcohol and drug abuse rehabilitation programs take place in a residential or inpatient location, where clientele remain for the duration of their rehabilitation which offers a more conducive treatment environment.
