Substance abuse treatment is offered in a wide variety of distinct treatment settings with a variety of different treatment methods. For example, some substance abuse treatment can be performed on an outpatient basis, where the person will typically receive 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 particularly helpful in handling more serious cases of addiction. Inpatient and residential substance abuse treatment can be done on a short term or long term basis, depending on unique circumstances which can be different for each person. Most substance abuse treatment will focus on getting the individual physically rehabilitated, and then concentrate on underlying psychological and emotional issues which will help them avoid relapse in the future.

Drug rehab programs which are offered 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 program. An outpatient drug rehab program provides many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug rehab program where the individual is required to stay and reside at the rehab 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 require a comprehensive aftercare program which will offer additional support and therapy to help them avoid relapse.
