Substance abuse treatment takes place in a wide variety of distinct 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 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 unique circumstances which can be different for each individual. Most substance abuse treatment will concentrate on getting the person physically rehabilitated, and then focus on underlying psychological and emotional issues which will help them avoid relapse in the future.
