Drug or alcohol rehab services which are delivered on an outpatient basis are available to addicted people who have circumstances which prevent them from being able to take part in an inpatient rehabilitation facility. An outpatient drug and alcohol rehabilitation center offers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug rehab center where the person is expected to stay and reside at the rehabilitation facility until the treatment process is complete. Outpatient drug treatment is also offered for those who have already gone through residential or inpatient treatment but also need a comprehensive aftercare program which will provide further support and treatment to help them remain clean and sober.
