People can become addicted to drugs no matter their handicap, disability or personal physical challenge. This sometimes makes people particularly more vulnerable to becoming involved in substance abuse, because of the difficult challenges that this can bring about in the individual'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 require ASL or other assistance as part of their treatment needs, and there are drug and alcohol rehabilitation 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.
