This paper examines barriers to health care utilization and the correlates associated with these barriers. As part of a larger study of health services utilization, the study sample of 1085 including injection drug users, other chronic users of heroin or cocaine, and a demographically similar group who had used neither heroin nor cocaine, was selected based on the criterion of not having received health care for at least one health problem within the previous 12 months. Both categories of chronic drug users were more likely than non-users not to want health care treatment and to put off seeking needed health care.
