Substance abuse treatment takes place in a wide variety of different treatment settings with a variety of different treatment approaches. For example, some substance abuse treatment can be performed 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 especially beneficial in resolving 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 person. Most substance abuse treatment will focus on getting the person physically rehabilitated, and then concentrate on underlying psychological and emotional issues.
