Drug treatment services which are delivered on an outpatient basis are available to addicted individuals who have circumstances which prevent them from being able to take part in an inpatient treatment center. An outpatient drug rehab center delivers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug or alcohol rehab facility where the individual is required to stay and reside at the rehabilitation program until treatment has been fully completed. Outpatient drug or alcohol rehab is also available for individuals who have completed residential or inpatient treatment but also need a thorough aftercare program which will provide additional support and treatment to help them remain clean and sober.
