Substance abuse treatment takes place in a wide range of different treatment settings with a variety of different treatment methods. For example, some substance abuse treatment can be carried out 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 especially helpful in resolving more severe 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 concentrate on getting the individual physically rehabilitated, and then focus on the root psychological and emotional issues.
