This infographic cites sources including the Substance Abuse and Mental Health Services Administration, the National Center for Biotechnology Information, and the National Institute on Drug Abuse to highlight the connection between drug or alcohol addiction and other mental disorders for a large number of individuals. It illustrates this connection with statistics such as the fact that individuals with mental illness are 2 times more likely to use illegal drugs and 3 times as likely to substance abuse or dependence as those without an underlying mental health condition. It further makes the point that individuals experiencing both substance abuse and mental illness require a coordinated approach in their care that addresses each of these issues in concert.
