Individuals may become addicted to alcohol or drugs no matter their handicap or personal physical problem. This often makes individuals significantly more susceptible to getting involved in alcohol or drug addiction, as a result of the unique issues that this can bring in the perspon's life. This is true for persons in the deaf and hearing impaired community also, and treatment for substance abuse issues is sometimes necessary. Deaf or hearing impaired persons will require ASL or other help as part of their treatment needs, and there are drug rehabilitation facilities accessible throughout the Markham area which specifically help fill these special needs. Professional drug rehab counselors who know ASL and can provide other necessary help to deaf or hearing impaired addicted individuals are readily available in a number of drug and alcohol rehabilitation programs around Markham and in the United States.
