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 carried out on an outpatient basis, where the person 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 handling more severe 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 focus on getting the individual physically rehabilitated, and then focus on underlying psychological and emotional issues which will help them avoid relapse in the future.
