Substance abuse treatment takes place 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 individual will typically attend 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 various circumstances which can be different for each individual. Most substance abuse treatment will concentrate on getting the individual physically rehabilitated, and then focus on underlying psychological and emotional issues which will help them avoid relapse in the future.
