Individuals can become addicted to drugs or alcohol no matter their handicap, disability or personal physical challenge. This sometimes makes individuals particularly more vulnerable to becoming involved in drug or alcohol use, because of the varying 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 individuals will require ASL or other assistance as part of their treatment needs, and there are drug rehabilitation facilities available which cater to these needs. Professional treatment counselors who know ASL and can offer other necessary assistance to deaf or hearing impaired substance abusers.
