The various drug and alcohol abuse treatment services which are available to drug and alcohol addicted people in Hartford can differ in many different ways. Some substance abuse rehabilitation programs are conducted in a residential or inpatient location, where individuals remain the entire time they are in treatment which offers a more conducive rehab environment. Others offer alcohol and drug abuse rehabilitation services on an outpatient basis which provides a sense of versatility, although outpatient programs are not always a suitable alcohol and drug abuse treatment service for individuals in Hartford who are having difficulties with long term drug or alcohol addiction difficulties. Regardless of whether inpatient or outpatient alcohol and drug abuse rehab services are chosen, there are also different amounts of time that people will be expected to continue to be in the alcohol and drug rehabilitation center. For example, quite a few short-term programs offer services for 4 weeks or less, whereas long-term programs will call for at least a 12 week stay.
