Usually abbreviated to IVDU or IDU. A term mainly applied to persons who use illicit street drugs, often under unhygienic conditions. Sharing needles with other users is a common feature of the subculture of IVDUs. Consequently, there is a high risk of transmitting blood-borne infections, including HIV and hepatitis B and C. Because many such persons finance their addiction by crime or prostitution, they may constitute a public health risk to others as well as endangering their own health.
