Drug treatment services 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 center. An outpatient drug rehab center delivers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug or alcohol rehab facility where the individual is required to stay and reside at the rehabilitation program until treatment has been fully completed. Outpatient drug or alcohol rehab is also available for individuals who have completed residential or inpatient treatment but also need a thorough aftercare program which will provide additional support and treatment to help them remain clean and sober.

Individuals can become addicted to drugs or alcohol no matter their handicap, disability or personal physical challenge. This sometimes makes individuals particularly more susceptible to becoming involved in drug or alcohol use, because of the various challenges that this can bring about in the person's life. This is true for those people in the deaf and hearing impaired community as well, and treatment for substance abuse and addiction is sometimes required. Deaf or hearing impaired persons will need ASL or other assistance as part of their treatment needs, and there are drug treatment centers available which cater to these needs. Professional substance abuse counselors who know ASL and can provide other necessary assistance to deaf or hearing impaired substance abusers.
