Drug or alcohol rehab programs which are delivered on an outpatient basis are readily available to addicted individuals who have circumstances which prevent them from being able to participate in an inpatient treatment program. An outpatient substance abuse rehab program 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 center until the treatment process is complete. Outpatient drug rehabilitation is also offered for individuals who have already gone through residential or inpatient treatment but also need a comprehensive aftercare and relapse prevention program which will provide additional support and treatment to help them remain clean and sober.
