Drug or alcohol treatment services which are delivered on an outpatient basis are readily available to addicted people who have circumstances which prevent them from being able to participate in an inpatient rehabilitation center. An outpatient substance abuse rehabilitation facility offers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug rehabilitation program where the individual is expected to remain at the treatment facility until treatment is complete. Outpatient drug rehab is also offered for individuals who have completed residential or inpatient treatment but also need a thorough aftercare and relapse prevention program which will offer additional support and therapy to help them remain clean and sober.
