Overview

Illicit use of drugs causes death and disability and is a risk factor for many diseases. It is also associated with risks to users' family and friends and to the community. Illicit use of drugs includes use of illegal drugs, misuse or non-medical use of pharmaceutical drugs, or inappropriate use of other substances (such as inhalants).

More reports and statistics on illicit use of drugs can be found under Alcohol, Alcohol & other drug treatment services and Smoking.
