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

Partial Hospitalization, also known as "PHP" or Day Treatment, is a type of rehabilitation program which works to treat substance abuse issues and mental health conditions which may be co-occurring. In a PHP program, the person in treatment participates in a variety of recovery activities and techniques during the day and then returns home in the evening. This is done anywhere from five to seven days a week, depending on the seriousness of the problem. Partial Hospitalization can be helpful for addicted persons who may not be able to afford long-term inpatient care, or who are unable to be away from their families for prolonged periods of time. While in Day Treatment, clients take part in typical counseling and therapy for addiction issues while also addressing mental health problems which could keep them from staying sober once treatment is complete.
