Substance abuse treatment takes place in a wide variety 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 receive treatment during the day but is allowed to return home daily. Other substance abuse treatment requires the person to stay in a hospital or residential facility during the entire course of treatment, which is particularly beneficial 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.

Drug or alcohol rehabilitation services which are offered on an outpatient basis are available to addicted people who have circumstances which prevent them from being able to participate in an inpatient treatment facility. An outpatient drug rehabilitation program provides many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug or alcohol treatment center where the individual is required to stay and reside at the treatment program until the treatment process is complete. Outpatient drug or alcohol treatment is also offered for those who have completed residential or inpatient treatment but require a comprehensive aftercare program which will offer additional support and treatment to help them avoid relapse.

Military health insurance normally refers to TRICARE and is a typically accepted insurance for particular drug treatment programs. A drug rehab that accepts military insurance will typically accept most other types of insurance as well. TRICARE commonly covers detoxification, rehabilitation and outpatient treatment.
