Substance abuse treatment takes place in a wide range of distinct treatment settings with a variety of different treatment methods. 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 reside in a hospital or residential facility during the entire course of treatment, which is particularly beneficial 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 various circumstances which can be different for each individual. Most substance abuse treatment will focus on getting the individual physically rehabilitated, and then focus on the root psychological and emotional issues which will help them avoid relapse in the future.

Drug treatment services which are offered on an outpatient basis are available to addicted people who have circumstances which prevent them from being able to take part in an inpatient rehab center. An outpatient drug treatment center provides many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug or alcohol rehab program where the individual is expected to remain at the rehabilitation 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 also need a comprehensive aftercare program which will offer further support and treatment to help them avoid relapse.
