"In summary, the present study demonstrates that the SIF was associated with increased use of detoxification service use and that residential detoxification was associated with increased rates of methadone use and other forms of addiction treatment. Given the known role of methadone and other forms of addiction treatment in reducing levels of injection drug use, and given that detoxification programme use was associated with reduced injecting at the SIF, our findings imply that the SIF has probably helped to reduce rates of injection drug use among users of the facility."
