The Association Between Self-Reported Non-Injection Cocaine Use and Hepatitis C in the United States: An Analysis of the National Health and Nutrition Examination Survey.

Objective: Previous studies conducted on hepatitis C virus (HCV) transmission have focused primarily on its transmission among people who inject drugs. However, there is evidence that transmission may also occur through the sharing of contaminated non-injection implements used to consume drugs nasally, orally, or by inhalation. Studies to date have not conclusively established a relationship between these routes of cocaine use and HCV.
