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

Persons with co-occurring mental and substance abuse disorders must address both issues in order to recover completely. Some individuals take drugs or alcohol to alleviate symptoms of mental health complications, and some individuals take drugs which then, in turn, brings about symptoms which mimic mental health problems, such as anxiety and depression. Drug rehabilitation professionals know how to distinguish between the two, and can work with clients to properly treat real mental health conditions in tandem with any other substance abuse treatment that is done with the person. This has proven to be effective in keeping individuals with mental health disorders off of drugs and mentally stable and healthy.
