Substance abuse treatment takes place in a wide variety of distinct treatment settings with a variety of different treatment approaches. For example, some substance abuse treatment can be done on an outpatient basis, where the individual will typically participate in treatment during the day but is allowed to return home daily. Other substance abuse treatment requires the individual to stay in a hospital or residential facility during the entire course of treatment, which is especially helpful in handling more severe cases of addiction. Inpatient and residential substance abuse treatment can be done on a short term or long term basis, depending on different circumstances which can be different for each individual. Most substance abuse treatment will concentrate on getting the person physically rehabilitated, and then concentrate on the root psychological and emotional issues which will help them avoid relapse in the future.

Drug or alcohol rehab services which are offered on an outpatient basis are readily available to addicted people who have circumstances which prevent them from being able to take part in an inpatient rehab facility. An outpatient drug treatment program offers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug rehabilitation facility where the person is required to stay and reside at the rehab center until the treatment process has been fully completed. Outpatient drug treatment is also offered for those who have completed residential or inpatient treatment but require a thorough aftercare and relapse prevention program which will offer additional support and treatment to help them avoid relapse.
