The Drug Treatment Outcomes Research Study (DTORS)

DTORS was carried out by the National Drug Evidence Centre (NDEC) in collaboration with the National Centre for Social Research (NatCen) on behalf of the Home Office.

The study is about people who are entering drug treatment programmes in England.  It aimed to find out what sort of things affect a person's chances of success in drug treatment programmes.  The information will be used to plan the provision of drug treatment and other services in this country, to help as many people as possible overcome their drug problems.
