The different alcohol and drug abuse rehab services which are accessible to drug and alcohol addicted individuals in Andover can vary in many different ways. Some drug and alcohol abuse rehab programs take place in a residential or inpatient setting, where individuals reside for the duration of their rehabilitation which provides a more therapeutic treatment environment. Others provide drug and alcohol abuse rehabilitation programs on an outpatient basis which provides a sense of flexibility, though outpatient centers are not always a suitable drug and alcohol abuse treatment program for men and women in Andover who are having difficulties with serious addiction issues. Whether inpatient or outpatient alcohol and drug abuse treatment services are chosen, there are also different amounts of time that people will be asked to remain in the drug rehab center. For example, many short-term programs offer services for 30 days or less, whereas long-term programs will require at least a 3 month stay.
