The ROSIE study: Drug treatment outcomes in Ireland.

The primary objective of this study (ROSIE - research outcome study in Ireland) was to evaluate the effectiveness of treatment and other intervention strategies for opiate use in Ireland. The Study recruited 404 opiate users entering treatment. Participants were interviewed at treatment intake, 1-year and 3 years after the baseline interview.
