Substance abuse treatment is offered in a wide variety of distinct treatment settings with a variety of different treatment approaches. For example, some substance abuse treatment can be carried out 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 person to reside in a hospital or residential facility during the entire course of treatment, which is particularly 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 different circumstances which can be different for each person. Most substance abuse treatment will focus on getting the individual physically rehabilitated, and then concentrate on the root psychological and emotional issues which will help them avoid relapse in the future.
