This longitudinal study focused on 126 long-term heroin users who had never been in specialist treatment for use of any drug. The primary aim of the study was to assess whether this ‘hidden’ population resembled heroin users identified with drug treatment agencies, or alternatively, to test whether heroin could indeed be used in a controlled, non-intrusive fashion for an extended period of time. Recruitment was achieved through chain-referred purposive sampling methods, and data were collected through two semi-structured interviews. 67% of participants were re-recruited for follow-up.
