Individuals may become addicted to alcohol or drugs no matter their handicap or unique physical problem. This often makes individuals significantly more vulnerable to becoming involved in alcohol or drug addiction, as a result of the unique challenges that this can bring in the individual's life. This is often a factor for persons in the deaf and hearing impaired community also, and drug rehab for substance abuse disorders is often needed. Deaf or hearing impaired people will need ASL or other help as part of their treatment program, and there are alcohol and drug treatment programs available throughout the Waterloo area which specifically help fill these special needs. Expert treatment counselors who know ASL and can provide other essential help to deaf or hearing impaired substance abusers are readily available in several drug and alcohol rehabilitation programs around Waterloo and in the country.
